A note on measuring apprehension about writing.

PubMed

Rechtien, J G; Dizinno, G

1997-06-01

Having revised Daly and Miller's 1975 unidimensional Writing Apprehension Test, Riffe and Stacks in 1992 proposed eight multidimensional factors derived from responses to 56 items in their Mass Communication Writing Apprehension Measure, administered to communication students to identify the various dimensions of apprehension about writing shared with business writers and specific to their major. The current authors administered the questionnaire at the beginning of an academic year to 419 freshmen from all undergraduate schools and majors at a private liberal arts university. It was hypothesized that the factors found among the homogeneous population of communication majors would not be replicated among the more heterogeneous student population. The hypothesis was partially upheld. Seven factors were identified. Two duplicated most items found by Riffe and Stacks (1992), four added items, and one was new. The results of this study suggest that, although the general population of students differs from students in mass communication, as Riffe and Stacks remarked, the groups also share similar content in their writing apprehension, that writing apprehension is multidimensional, that caution must be exercised when administering any instrument for the diagnostic and counseling purposes suggested by Riffe and Stacks, and that writing apprehension should also be investigated from the perspective of locus of control.

"Playing Hooky" Health Messages: Apprehension, Impression Management, and Deception.

PubMed

Barrett, Ashley; Murphy, Melissa; Blackburn, Kate

2018-03-01

This study investigates playing hooky in higher education classrooms and associates this behavior with students' communicative dispositions, instructor perceptions, and language use. We define "playing hooky" as students skipping class and explaining their absence to their instructor with deceptive health messages. The purpose of Study 1, an online survey (N = 177), is to further understand the characteristics of students who engage in this type of deceptive health communication. Study 1 measures communication apprehension and perceived instructor credibility in students who had played hooky from class and those who had not. Findings reveal that students who communicate playing hooky health messages (a) reported more instructor communication apprehension and (b) perceived the instructors with whom they had played hooky to be less credible. Study 2 uses facework theory and MEH analysis to reveal the different linguistic strategies students use to communicate (a) truthful health messages (N = 165) and (b) deceptive heath messages (N = 82) to their instructor following an absence. Results demonstrate that students' facework strategies are more geared toward saving instructors' negative face in the deceptive health message condition. Implications of both studies are offered.

Predictors of disability-related attitudes: considering self-esteem, communication apprehension, contact, and geographic location

PubMed Central

Magsamen-Conrad, Kate; Tetteh, Dinah; Lee, Yen-I

2016-01-01

Individuals’ attitudes about persons with disability (PwD) strongly affect differently-abled persons’ quality of life and position in society. Some research offers support for the ability of systematic, supported, longitudinal contact between different groups of individuals to improve attitudes. College campuses, in particular, offer a potentially useful arena in which to facilitate this type of contact. This study explored contextual factors (eg, geographic region, biological sex) and predictors of disability-related attitudes among a college student population to determine strategies for course-based intervention design (eg, as community-engaged or service-learning initiatives). Surveying participants from universities in two regions of the United States, we found that self-esteem, audience-based communication apprehension, and contact with PwD explain more than 50% of the variance in disability-related attitudes. Further, we found that geographic location affects both self-esteem and audience-based communication apprehension (communicating/interacting with PwD). We discuss the implications for community engagement and/or service learning and highlight the importance of partnerships among relevant community stakeholders, including university faculty, students, and staff.

Racial Differences in Communication Apprehension and Interprofessional Socialization in Fourth-Year Doctor of Pharmacy Students

PubMed Central

Karpinski, Aryn C.

2016-01-01

Objective. To examine racial differences in communication apprehension and interprofessional socialization in fourth-year PharmD students and to investigate the relationship between the two constructs. Methods. Two measures with reliability and validity psychometric evidence were administered to fourth-year pharmacy students at a single historically black university with a large racial minority population. The Personal Report of Communication Apprehension (PRCA-24) measures level of fear or anxiety associated with communication. The Interprofessional Socialization and Valuing Scale (ISVS) measures beliefs, attitudes, and behaviors towards interprofessional collaborative practice. Results. One hundred fourteen students completed the survey. This produced a 77.4% response rate and 45.6% of the participants were African American. There were significant differences between races (ie, White, African-American, and Asian) on both measures. The PCRA-24 and ISVS were significantly correlated in each racial group. Conclusion. As pharmacy education moves to more interprofessional collaborations, the racial differences need to be considered and further explored. Pharmacy curricula can be structured to promote students’ comfort when communicating interprofessionally across racial groups. Understanding of culture and early education in cultural competence may need to be emphasized to navigate racial or cultural differences. PMID:26941434

Public speaking attitudes: does curriculum make a difference?

PubMed

Hancock, Adrienne B; Stone, Matthew D; Brundage, Shelley B; Zeigler, Mark T

2010-05-01

In light of infamous levels of fear associated with public speaking, businesses are training staff in communication effectiveness and universities are requiring courses in public speaking. A variety of approaches to individual training are available, but few studies have assessed effectiveness of group instruction, as in academic curricula. The specific purpose of this study was to compare changes in scores on measures of self-perceived confidence, competence, and apprehension associated with public speaking after two types of courses: one focused on knowledge of the vocal mechanism and mastering vocal characteristics (pitch, volume, rate, quality), and one addressing general communication theory and public speaking. Seventy-one undergraduate students enrolled in "Voice and Diction" at George Washington University (GWU) and 68 enrolled in "Fundamental Speech" at Florida State University completed questionnaires before and after the courses. Scores on Self-Perceived Communication Competence Scale, Personal Report of Confidence as a Speaker, and Personal Report of Communication Apprehension-24, were compared within subjects (ie, prepost course) and between courses. Significant differences (p<0.05) were found on all measures: students reported less apprehension and more confidence and competence after the courses. No differences were found between the two courses when comparing the mean changes from pre- to postscore. Traditional public speaking curriculum of how to design and deliver a speech and curriculum tailored to the voice and speech mechanism succeeded in reducing public speaking apprehension and increasing feelings of confidence and competency for these undergraduate students.

2011-12-01

This study explores whether and how gratifications and psychological traits impact people's Facebook use. First, a factor analysis of an online survey (N= 437) outlined a unique set of gratifications obtained from the use of Facebook. Six aspects of gratifications (i.e., social surveillance, entertainment, recognition, emotional support, network extension, and maintenance) were identified. Results from regression analyses showed that psychological traits (i.e., collective self-esteem, online emotional openness, and traitlike communication apprehension) were strong predictors of most Facebook gratifications. Additionally, gratifications and, to a lesser extent, psychological traits significantly predicted Facebook usage, both in perceived importance and different indicators in the level of Facebook use.

Being comfortable with death and communicating with patients near the end of life are important attributes in palliative care. We developed a hospice volunteer program to teach these attitudes and skills to preclinical medical students. Using a mixed-methods approach, validated surveys measured participants' and non-participants fear of death and communication apprehension regarding dying. Journals and focus groups examined participants' subjective experiences as their patient relationships evolved. Survey scores were significantly lower for participant hospice volunteers, indicating lower levels of death anxiety and communication apprehension regarding dying. An explanatory framework, using journals and focus groups, captured participants' sense of development over time into three categories: challenges, learning, and growth. This pilot project provides insight into the medical students' experiential learning as they participate in our hospice volunteer program.

The art of talking about science: beginning to teach physiology students how to communicate with nonscientists.

PubMed

Petzold, Andrew M; Dunbar, Robert L

2018-06-01

The ability to clearly disseminate scientific knowledge is a skill that is necessary for any undergraduate student within the sciences. Traditionally, this is accomplished through the instruction of scientific presentation or writing with a focus on peer-to-peer communication at the expense of teaching communication aimed at a nonscientific audience. One of the ramifications of focusing on peer-to-peer communication has presented itself as an apprehension toward scientific knowledge within the general populace. This apprehension can be seen in a variety of venues, including the traditional media, popular culture, and education, which generally paint scientists as aloof and with an inability to discuss scientific issues to anyone other than other scientists. This paper describes a curriculum designed to teach Introduction to Anatomy and Physiology students the tools necessary for communicating complex concepts that were covered during the semester using approachable language. Students were assessed on their word usage in associated writing activities, the student's ability to reduce complexity of their statements, and performance in an informal scientific presentation to a lay audience. Results showed that this pedagogical approach has increased students' ability to reduce the complexity of their language in both a written and oral format. This, in turn, led to evaluators reporting greater levels of understanding of the topic presented following the presentation.

Learning About Dying and Living: An Applied Approach to End-of-Life Communication.

PubMed

Pagano, Michael P

2016-08-01

The purpose of this article is to expand on prior research in end-of-life communication and death and dying communication apprehension, by developing a unique course that utilizes a hospice setting and an applied, service-learning approach. Therefore, this essay describes and discusses both students' and my experiences over a 7-year period from 2008 through 2014. The courses taught during this time frame provided an opportunity to analyze students' responses, experiences, and discoveries across semesters/years and cocultures. This unique, 3-credit, 14-week, service-learning, end-of-life communication course was developed to provide an opportunity for students to learn the theories related to this field of study and to apply that knowledge through volunteer experiences via interactions with dying patients and their families. The 7 years of author's notes, plus the 91 students' electronically submitted three reflection essays each (273 total documents) across four courses/years, served as the data for this study. According to the students, verbally in class discussions and in numerous writing assignments, this course helped lower their death and dying communication apprehension and increased their willingness to interact with hospice patients and their families. Furthermore, the students' final research papers clearly demonstrated how utilizing a service-learning approach allowed them to apply classroom learnings and interactions with dying patients and their families at the hospice, to their analyses of end-of-life communication theories and behaviors. The results of these classes suggest that other, difficult topic courses (e.g., domestic violence, addiction, etc.) might benefit from a similar pedagogical approach.

Nursing students' reading and English aptitudes and their relationship to discipline-specific formal writing ability: a descriptive correlational study.

PubMed

Newton, Sarah; Moore, Gary

2010-01-01

Formal writing assignments are commonly used in nursing education to develop students' critical thinking skills, as well as to enhance their communication abilities. However, writing apprehension is a common phenomenon among nursing students. It has been suggested that reading and English aptitudes are related to formal writing ability, yet neither the reading nor the English aptitudes of undergraduate nursing students have been described in the literature, and the relationships that reading and English aptitude have with formal writing ability have not been explored. The purpose of this descriptive correlational study was to describe writing apprehension and to assess the relationships among reading and English aptitude and discipline-specific formal writing ability among undergraduate nursing students. The study sample consisted of 146 sophomores from one baccalaureate nursing program. The results indicated that both reading and English aptitude were related to students' formal writing ability.

Object apprehension using vision and touch

NASA Technical Reports Server (NTRS)

Bajcsy, R.; Stansfield, S. A.

1987-01-01

Researchers define object apprehension as the determination of the properties of an object and the relationships among these properties. They contrast this with recognition, which goes a step further to attach a label to the object as a whole. Apprehension is fundamental to manipulation. This is true whether the manipulation is being carried out by an autonomous robot or is the result of teleoperation involving sensory feedback. Researchers present an apprehension paradigm using both vision and touch. In this model, they define a representation for object apprehension in terms of a set of primitives and features, along with their relationships. This representation is the mechanism by which the data from the two modalities are combined. It is also the mechanism which drives the apprehension process.

Tennis elbow is a syndrome that commonly diagnosed in patient who comes with lateral elbow pain. Instability pain in tennis elbow patient was observed and reported in many previous literatures. Posterolateral rotatory apprehension test was proposed for diagnosis of posterolateral rotatory instability of elbow. However, no review literatures that studied about posterolateral rotatory apprehensions test in tennis elbow. To find out the relationship between posterolateral rotatory apprehension test and tennis elbow. There were 44 patients that were recruited in this study. We examined the posterolateral rotatory apprehension test in tennis elbow patients. The examination was done in our outpatient clinic from March 2012 to April 2012. The data was collected to find out the ratio of negative test in tennis elbow patient. The results from the posterolateral rotatory apprehension test were negative in 43 patients. The ratio of the negative test result was 98%. A result from posterolateral rotatory apprehension test should be negative in general tennis elbow patients. If this test is used in a tennis elbow patients who are suspected with hidden instability and the result is positive, further evaluation is strongly suggested.

Resting-State Functional Connectivity Differentiates Anxious Apprehension and Anxious Arousal

Burdwood, Erin N.; Infantolino, Zachary P.; Crocker, Laura D.; Spielberg, Jeffrey M.; Banich, Marie T.; Miller, Gregory A.; Heller, Wendy

2016-01-01

Brain regions in the default mode network (DMN) display greater functional connectivity at rest or during self-referential processing than during goal-directed tasks. The present study assessed resting-state connectivity as a function of anxious apprehension and anxious arousal, independent of depressive symptoms, in order to understand how these dimensions disrupt cognition. Whole-brain, seed-based analyses indicated differences between anxious apprehension and anxious arousal in DMN functional connectivity. Lower connectivity associated with higher anxious apprehension suggests decreased adaptive, inner-focused thought processes, whereas higher connectivity at higher levels of anxious arousal may reflect elevated monitoring of physiological responses to threat. These findings further the conceptualization of anxious apprehension and anxious arousal as distinct psychological dimensions with distinct neural instantiations. PMID:27406406

Although shoulder apprehension is an established clinical finding and is important for the prevention of shoulder dislocation, how this subjective perception is evoked remains unclear. We elucidated the functional neuroplasticity associated with apprehension in patients with recurrent anterior shoulder instability (RSI) using functional magnetic resonance imaging (fMRI). Twelve healthy volunteers and 14 patients with right-sided RSI performed a motor imagery task and a passive shoulder motion task. Brain activity was compared between healthy participants and those with RSI and was correlated with the apprehension intensity reported by participants after each task. Compared to healthy volunteers, participants with RSI exhibited decreased brain activity in the motor network, but increased activity in the hippocampus and amygdala. During the passive motion task, participants with RSI exhibited decreased activity in the left premotor and primary motor/somatosensory areas. Furthermore, brain activity was correlated with apprehension intensity in the left amygdala and left thalamus during the motor imagery task (memory-induced), while a correlation between apprehension intensity and brain activity was found in the left prefrontal cortex during the passive motion task (instability-induced). Our findings provide insight into the pathophysiology of RSI by identifying its associated neural alterations. We elucidated that shoulder apprehension was induced by two different factors, namely instability and memory. PMID:26351854

1993-12-01

This thesis is an exploratory study of Neuro-Linguistic Programming (NLP), and its capabilities to provide a technique or a composite technique that will reduce the anxiety associated with making an oral brief or presentation before a group, sometimes referred to as Communication Apprehension. The composite technique comes from NLP and Time Line Therapy, which is an extension to NLP. Student volunteers (17) from a Communications course given by the Administrative Sciences Department were taught this technique. For each volunteer, an informational oral presentation was made and videotaped before the training and another informational oral presentation made and videotaped following the training. The before and after training presentations for each individual volunteer were evaluated against criteria for communications anxiety and analyzed to determine if there was a noticeable reduction of anxiety after the training. Anxiety was reduced in all of the volunteers in this study.

2014-01-01

The number of children in care of the state continues to grow in BC, Canada with a historical legacy of child apprehension among criminalized and marginalized populations, particularly women of Aboriginal ancestry and sex workers. However, there is a paucity of research investigating child apprehension experiences among marginalized mothers. The objective of the current analysis is to examine the prevalence and correlates of child apprehensions among female sex workers in Vancouver, Canada. Analyses were drawn from the AESHA (An Evaluation of Sex Workers Health Access, 2010-present), a prospective cohort of street and off-street SWs, through outreach and semi-annual visits to the research office. Bivariate and multivariate logistic regression were used to examine correlates of child apprehension. Of a total of 510 SWs, 350 women who had given birth to at least one child were included in the analyses (median age = 37 yrs: IQR: 31-44 yrs). The prevalence of child apprehension among mothers was 38.3%, with 37.4% reporting having been apprehended themselves by child welfare services. In multivariable analysis, servicing clients in outdoor public spaces (versus formal sex work establishments or informal indoor settings) (adjusted odds ratio, (aOR) = 2.73; 95%CI 1.27-5.90), history of injecting drugs (aOR  = 2.53; 95%CI 1.42-4.49), Aboriginal ancestry (aOR = 1.66; 95%CI 1.01-2.74) were associated with increased odds of child apprehension. Child apprehension rates are high, particularly among the most marginalized sex workers, including sex workers who use drugs and sex workers of Aboriginal ancestry. Structural reforms to child protection are urgently needed, that support family-based care address the historical legacy of colonization affecting Aboriginal peoples.

Our understanding of the biopsychosocial model of health, and its influence on chronic endocrine conditions, has improved over the past few decades. We can distinguish, for example, between diabetes distress and major depressive disorders in diabetes. Similar to diabetes distress, we suggest the existence of "thyrostress" in chronic thyroid disorders. Thyro-stress is defined as an emotional state, characterized by extreme apprehension, discomfort or dejection, caused by the challenges and demand of living with thyroid disorders such as hypothyroidism. This communication describes the etiology, clinical features, differential diagnosis, and management of thyro-stress.

Dynamics of contraceptive use in India: apprehension versus future intention among non-users and traditional method users.

PubMed

Rai, Rajesh Kumar; Unisa, Sayeed

2013-06-01

This study examines the reasons for not using any method of contraception as well as reasons for not using modern methods of contraception, and factors associated with the future intention to use different types of contraceptives in India and its selected states, namely Uttar Pradesh, Assam and West Bengal. Data from the third wave of District Level Household and Facility Survey, 2007-08 were used. Bivariate as well as logistic regression analyses were performed to fulfill the study objective. Postpartum amenorrhea and breastfeeding practices were reported as the foremost causes for not using any method of contraception. Opposition to use, health concerns and fear of side effects were reported to be major hurdles in the way of using modern methods of contraception. Results from logistic regression suggest considerable variation in explaining the factors associated with future intention to use contraceptives. Promotion of health education addressing the advantages of contraceptive methods and eliminating apprehension about the use of these methods through effective communication by community level workers is the need of the hour.

Objectives The number of children in care of the state continues to grow in BC, Canada with a historical legacy of child apprehension among criminalized and marginalized populations, particularly women of Aboriginal ancestry and sex workers. However, there is a paucity of research investigating child apprehension experiences among marginalized mothers. The objective of the current analysis is to examine the prevalence and correlates of child apprehensions among female sex workers in Vancouver, Canada. Methods Analyses were drawn from the AESHA (An Evaluation of Sex Workers Health Access, 2010-present), a prospective cohort of street and off-street SWs, through outreach and semi-annual visits to the research office. Bivariate and multivariate logistic regression were used to examine correlates of child apprehension. Results Of a total of 510 SWs, 350 women who had given birth to at least one child were included in the analyses (median age = 37 yrs: IQR: 31–44 yrs). The prevalence of child apprehension among mothers was 38.3%, with 37.4% reporting having been apprehended themselves by child welfare services. In multivariable analysis, servicing clients in outdoor public spaces (versus formal sex work establishments or informal indoor settings) (adjusted odds ratio, (aOR) = 2.73; 95%CI 1.27–5.90), history of injecting drugs (aOR = 2.53; 95%CI 1.42–4.49), Aboriginal ancestry (aOR = 1.66; 95%CI 1.01–2.74) were associated with increased odds of child apprehension. Discussion/Conclusions Child apprehension rates are high, particularly among the most marginalized sex workers, including sex workers who use drugs and sex workers of Aboriginal ancestry. Structural reforms to child protection are urgently needed, that support family-based care address the historical legacy of colonization affecting Aboriginal peoples. PMID:24927324

AIDS: The Role of Imaging Modalities and Infection Control Policies

The availability of imaging modalities, such as the chest radiograph, gallium scan, double-contrast barium enema, computed tomography, and nuclear magnetic resonance, are very helpful in the diagnosis, treatment, and follow-up evaluation of patients with acquired immunodeficiency syndrome (AIDS). Because this syndrome causes irreversible destruction of the immune system, patients are susceptible to a multitude of opportunistic infections and malignancies. Health care professionals and the general public would be less fearful and apprehensive of AIDS victims if properly informed about the communicability of this syndrome. PMID:3047412

Entry-level physical therapists provide clinical care for patients with functional mobility limitations. Their care spans the continuum of settings, disease processes, and diagnoses. Although effective communication skills are required to conduct physical therapy work, there is limited instruction provided in physical therapy education and students receive little exposure to seriously or chronically ill patients. The goal of this study was to assess the effects of communication training for the entry-level physical therapist facing palliative and end-of-life communication with patients/families. A pre-post survey design and narrative writing were used to assess the effect of the COMFORT communication training curriculum provided to doctorally trained, graduating physical therapists. The study demonstrated decreased student apprehension about communicating with dying patients and their families, and a comparison of mean scores reflecting the students' communication knowledge, confidence, and behaviors increased in a positive direction. As students became more willing to communicate, they were also more adept at integrating task and relational messages, as well as assimilating emotional support messages for patients and families. This study shows promise for the feasibility and utilization of the COMFORT curriculum for entry-level physical therapists. Further research should address the integration of COMFORT earlier into physical therapy education, as well as assess evidence of COMFORT communication skills in the clinical context.

Research has recently identified a promising neurophysiological marker of approach motivation involving posterior versus frontal (Pz-Fz) electroencephalographic (EEG) theta activity (PFTA; Wacker, Chavanon, & Stemmler, 2006). Preliminary evidence indicates that PFTA is modulated by dopaminergic activity thought to underlie appetitive tendencies, and that it indexes self-reported Behavioral Approach System (BAS) sensitivity. To date, research has largely relied on resting indices of PFTA and has yet to examine the relationship between PFTA and specific approach-related affective states generated by emotionally salient laboratory tasks. Accordingly, the present study evaluated PFTA both at rest and during an ecologically valid autobiographical memory task in which participants recalled personal life experiences involving a goal-striving, an anxious apprehension, a low-point (i.e., difficult) and a neutral memory while EEG data were recorded. In line with prediction, elevated PFTA was observed during both goal-striving and anxious apprehension autobiographical memories. PFTA was particularly elevated during anxious apprehension memories coded as being high on approach-related tendencies. Elevated PFTA during anxious apprehension is consistent with a growing literature indicating that anxious apprehension is associated with elevated approach and reward-related brain function. Lastly, elevated resting PFTA was positively correlated with self-reported trait anger, a negatively valenced emotion characterized by approach-related tendencies. Results have implications for a) enhancing our understanding of the neurophysiology of approach-related emotions, b) establishing PFTA as an index of appetitive motivational states, and c) clarifying our understanding of the neurophysiology and approach-related tendencies associated with both anxious apprehension and anger.

Previous studies obtained mixed results regarding the association between collectivism and corruption. To make sense of the mixed results, the current research examined the moderating role of evaluation apprehension on the relationship between collectivism and corruption. Study 1, using a bribery scenario, indicated that collectivism facilitated corruption only when evaluation apprehension was low. Study 2, using a real money bribery game, confirmed the moderated model found in Study 1. Study 3 further demonstrated the different effects of vertical/horizontal collectivism on corruption. Our results suggest that a society may effectively combat corruption by increasing its social costs while, at the same time, retaining its collectivistic values. PMID:25815819

The arrival of Zika virus in the United States has generated a lot of activity on social media focusing on the algorithmic increase in the spread of the disease and its concerning complications. Accurate and credible dissemination of correct information about the arbovirus could help in decreasing the pandemic spread and associated apprehension in the population. Our study examined the effective use of the social media site Facebook (Facebook Inc, Menlo Park, CA) as an information source for the Zika virus pandemic. We found that the misleading posts were far more popular than the posts dispersing accurate, relevant public health information about the disease.

2013-04-01

The internet is a phenomena that changes human, specially the younger generation's, life in the 21(st) century. Online communication is a common way of interacting among adolescents who experience feelings of social anxiety. The aim of this study was to investigate the relationship between social anxiety and online communication in adolescents. Three hundred and thirty students aged 13-16 years were selected from eight middle and high schools in Isfahan by multistage cluster sampling. Each of them completed a survey on the amount of time they spent communicating online, the topics they discussed, the partners they engaged with and their purpose for communicating over the internet. They also completed the social anxiety scale of adolescents. Data were analyzed using Pearson correlation and multiple regression. Results of the Pearson analysis showed that online communication has a significant positive relationship with apprehension and fear of negative evaluation (AFNE), and a significant negative relationship with tension and inhibition in social contact (TISC) (P < 0.01). The results of regression analysis showed that the best predictor of online communication is AFNE, TISC. It is suggested that students from middle school get assessed in terms of the level of social anxiety. Then, the quality and quantity of their online communication should be moderated through group training and consulting and referral to medical centers, if needed. The results of this study may lead to optimal use of online communications and reduce the personal, social and psychological problems of adolescents.

Disruption or innovation? A qualitative descriptive study on the use of electronic patient-physician communication in patients with advanced cancer.

PubMed

Voruganti, Teja; Husain, Amna; Grunfeld, Eva; Webster, Fiona

2018-03-04

In the advanced cancer context, care coordination is often inadequate, leading to suboptimal continuity of care. We evaluated an electronic web-based tool which assembles the patient, their caregivers, and their healthcare providers in a virtual space for team-based communication. We sought to understand participant perceptions on electronic communication in general and the added value of the new tool in particular. We conducted a qualitative descriptive study with participants (patients, caregivers, cancer physicians) who participated in a 3-month pilot trial evaluating the tool. Interviews were thematically analyzed and the perspectives from patients, caregivers, and cancer physicians were triangulated. Interviews from six patients, five of their caregivers, and seven cancer physicians conducted alongside monthly outcome assessments were analyzed. We identified five themes relating participants' perspectives on electronic communication to their experience of care: (1) apparent gaps in care, (2) uncertainty in defining the circle of care, (3) relational aspects of communication, (4) incongruence between technology and social norms of patient-physician communication, and (5) appreciation but apprehension about the team-based communication tool for improving the experience of care. The potential of tools for electronic communication to bring together a team of healthcare providers with the patient and caregivers is significant but may pose new challenges to existing team structure and interpersonal dynamics. Patients and physicians were worried about the impact that electronic communication may have on the patient-physician relationship. Implementation approaches, which build on the relationship and integrate the team as a whole, could positively position electronic communication to enhance the team-based care.

Evaluation Apprehension and Impression Management in Clinical Medical Education.

PubMed

McGaghie, William C

2018-05-01

Historically, clinical medical education has relied on subjective evaluations of students and residents to judge their clinical competence. The uncertainty associated with these subjective clinical evaluations has produced evaluation apprehension among learners and attempts to manage one's professional persona (impression management) among peers and supervisors. Such behavior has been documented from antiquity through the Middle Ages to the present, including in two new qualitative studies in this issue of Academic Medicine on the social psychology of clinical medical education. New approaches to medical education, including competency-based education, mastery learning, and assessment methods that unite evaluation and education, are slowly changing the culture of clinical medical education. The author of this Invited Commentary argues that this shift will bring greater transparency and accountability to clinical medical education and gradually reduce evaluation apprehension and the impression management motives it produces.

Specificity of regional brain activity in anxiety types during emotion processing.

PubMed

Engels, Anna S; Heller, Wendy; Mohanty, Aprajita; Herrington, John D; Banich, Marie T; Webb, Andrew G; Miller, Gregory A

2007-05-01

The present study tested the hypothesis that anxious apprehension involves more left- than right-hemisphere activity and that anxious arousal is associated with the opposite pattern. Behavioral and fMRI responses to threat stimuli in an emotional Stroop task were examined in nonpatient groups reporting anxious apprehension, anxious arousal, or neither. Reaction times were longer for negative than for neutral words. As predicted, brain activation distinguished anxious groups in a left inferior frontal region associated with speech production and in a right-hemisphere inferior temporal area. Addressing a second hypothesis about left-frontal involvement in emotion, distinct left frontal regions were associated with anxious apprehension versus processing of positive information. Results support the proposed distinction between the two types of anxiety and resolve an inconsistency about the role of left-frontal activation in emotion and psychopathology.

Discovering communicative competencies in a nonspeaking child with autism.

PubMed

Stiegler, Lillian N

2007-10-01

This article is intended to demonstrate that adapted conversation analysis (CA) and speech act analysis (SAA) may be applied by speech-language pathologists (SLPs) to (a) identify communicative competencies in nonspeaking children with autism spectrum disorder (ASD), especially during particularly successful interactions, and (b) identify communicative patterns that are exhibited by interventionists and communication partners that may positively or negatively impact interactions with such children. A case example involving an 8-year-old boy with autism and the author, an SLP, is explicated. A videotaped segment from an intervention session was transcribed and subjected to adapted forms of CA and SAA. CA and SAA helped reveal several underlying competencies in the boy's communicative output, including an awareness of conversational structure and sequence, diversity of communicative acts, functional use of gaze and smile behavior, and the ability to spontaneously initiate interactions. Observations regarding the SLP's interactive style included the use of multiple instances of "asking" as well as multiple "derailments" of the boy's obvious communicative bids. CA and SAA may be adapted to gain a clearer picture of what takes place during especially positive communicative interactions with nonspeaking children with ASD.

Prescription drug abuse communication: A qualitative analysis of prescriber and pharmacist perceptions and behaviors.

PubMed

Hagemeier, Nicholas E; Tudiver, Fred; Brewster, Scott; Hagy, Elizabeth J; Hagaman, Angela; Pack, Robert P

Interpersonal communication is inherent in a majority of strategies seeking to engage prescriber and pharmacist health care professionals (HCPs) in the reduction and prevention of prescription drug abuse (PDA). However, research on HCP PDA communication behavioral engagement and factors that influence it is limited. This study quantitatively examined communication behaviors and trait-level communication metrics, and qualitatively described prescription drug abuse-related communication perceptions and behaviors among primary care prescribers and community pharmacists. Five focus groups (N = 35) were conducted within the Appalachian Research Network (AppNET), a rural primary care practice-based research network (PBRN) in South Central Appalachia between February and October, 2014. Focus groups were structured around the administration of three previously validated trait-level communication survey instruments, and one instrument developed by the investigators to gauge HCP prescription drug abuse communication engagement and perceived communication importance. Using a grounded theory approach, focus group themes were inductively derived and coded independently by study investigators. Member-checking interviews were conducted to validate derived themes. Respondents' trait-level communication self-perceptions indicated low communication apprehension, high self-perceived communication competence, and average willingness to communicate as compared to instrument specific criteria and norms. Significant variation in HCP communication behavior engagement was noted specific to PDA. Two overarching themes were noted for HCP-patient communication: 1) influencers of HCP communication and prescribing/dispensing behaviors, and 2) communication behaviors. Multiple sub-themes were identified within each theme. Similarities were noted in perceptions and behaviors across both prescribers and pharmacists. Despite the perceived importance of engaging in PDA communication, HCPs reported that prescription drug abuse communication is uncomfortable, variable, multifactorial, and often avoided. The themes that emerged from this analysis support the utility of communication science and health behavior theories to better understand and improve PDA communication behaviors of both prescribers and pharmacists, and thereby improve engagement in PDA prevention and treatment.

Luetsch, Karen; Rowett, Debra

2015-10-01

Interprofessional communication skills are important for pharmacists to build collaborative relationships with other health professionals, integrate into healthcare teams, maximise their effectiveness in patient care in addressing complex care needs and meet the demands of health care reforms. This qualitative study explores clinical pharmacists' experiences and reflections after completing a learning and practice module which introduced them to a framework for successful interprofessional communication. The postgraduate clinical pharmacy program at The University of Queensland and the clinical pharmacy practice environments of forty-eight hospital and seven community based pharmacists. A learning and practice module outlining a framework for successful interprofessional communication was designed and integrated into a postgraduate clinical pharmacy program. Enrolled pharmacists applied newly learnt communication skills in pro-actively initiated, clinical discussions with a health professional in their practice environment. They provided written reflections on their experiences which were analysed using thematic analysis. Pharmacists' perceptions of the impact of applying the communication framework during their interaction with a health professional in their practice setting. Themes which emerged from reflections described pharmacists' confidence and capabilities to successfully conduct a clinical discussion with a health professional after initial apprehension and nervousness about the scheduled interaction. The application of the communication framework enhanced their perception of their professional identity, credibility and ability to build a collaborative working relationship with other health professionals. Pharmacists perceived that a learning and practice module for successful interprofessional practice integrated into a postgraduate clinical pharmacy program enhanced their interprofessional communication skills. The development of pro-active, interprofessional communication skills has the potential to increase interprofessional collaboration and pharmacists' personal role satisfaction. Pharmacists also observed it added value to their professional contribution in health care teams when addressing the demands of increasingly complex health care needs and reforms.

Acute Slices of Mice Testis Seminiferous Tubules Unveil Spontaneous and Synchronous Ca2+ Oscillations in Germ Cell Clusters1

ABSTRACT Spermatogenic cell differentiation involves changes in the concentration of cytoplasmic Ca2+ ([Ca2+]i); however, very few studies exist on [Ca2+]i dynamics in these cells. Other tissues display Ca2+ oscillations involving multicellular functional arrangements. These phenomena have been studied in acute slice preparations that preserve tissue architecture and intercellular communications. Here we report the implementation of intracellular Ca2+ imaging in a sliced seminiferous tubule (SST) preparation to visualize [Ca2+]i changes of living germ cells in situ within the SST preparation. Ca2+ imaging revealed that a subpopulation of male germ cells display spontaneous [Ca2+]i fluctuations resulting from Ca2+ entry possibly throughout CaV3 channels. These [Ca2+]i fluctuation patterns are also present in single acutely dissociated germ cells, but they differ from those recorded from germ cells in the SST preparation. Often, spontaneous Ca2+ fluctuations of spermatogenic cells in the SST occur synchronously, so that clusters of cells can display Ca2+ oscillations for at least 10 min. Synchronous Ca2+ oscillations could be mediated by intercellular communication via gap junctions, although intercellular bridges could also be involved. We also observed an increase in [Ca2+]i after testosterone application, suggesting the presence of functional Sertoli cells in the SST. In summary, we believe that the SST preparation is suitable to explore the physiology of spermatogenic cells in their natural environment, within the seminiferous tubules, in particular Ca2+ signaling phenomena, functional cell-cell communication, and multicellular functional arrangements.

Risk communication considerations to facilitate the screening of mass populations for potential contamination with radioactive material.

PubMed

Emery, R J; Sprau, D D; Morecook, R C

2008-11-01

Experience gained during a field training exercise with a Medical Reserve Corps unit on the screening of large groups of individuals for possible contamination with radioactive material revealed that while exercise participants were generally attentive to the proper use of protective equipment and detectors, they tended to overlook important basic risk communications aspects. For example, drill participants did not actively communicate with the persons waiting in line for screening, a step which would provide re-assurance, possibly minimize apprehension, and would clarify expectations. When questioned on this issue of risk communication, drill participants were often able to craft ad hoc messages, but the messages were inconsistent and likely would not have significantly helped diminish anxiety and maintain crowd control. Similar difficulties were encountered regarding messaging for persons determined to be contaminated, those departing the screening center, and those to be delivered to the media. Based on these experiences, the need for a suggested list of risk communication points was identified. To address this need, a set of risk communication templates were developed that focused on the issues likely to be encountered in a mass screening event. The points include issues such as the importance of remaining calm, steps for minimizing possible intake or uptake, considerations for those exhibiting acute injuries, expected screening wait times, the process to be followed and the information to be collected, the process to be undertaken for those exhibiting contamination, and symptoms to watch for after departure. Drill participants indicated in follow-up discussions that such pre-established risk communication templates would serve to enhance their ability to assist in times of emergency and noted the potential broader applicably of the approach for use in responses for other disasters types as well.

Frameworks for clinical communication assist educators in making explicit the principles of good communication and providing feedback to medical trainees. However, existing frameworks rarely take into account the roles of culture and language in communication, which can be important for international medical graduates (IMGs) whose first language is not English. This article describes the collaboration by a medical educator, a discourse analyst, and a phonetician to develop a communication and language feedback methodology to assist IMG trainees at a Victorian hospital in Australia with developing their doctor-patient communication skills. The Communication and Language Feedback (CaLF) methodology incorporates a written tool and video recording of role-plays of doctor-patient interactions in a classroom setting or in an objective structured clinical examination (OSCE) practice session with a simulated patient. IMG trainees receive verbal feedback from their hospital-based medical clinical educator, the simulated patient, and linguists. The CaLF tool was informed by a model of language in context, observation of IMG communication training, and process evaluation by IMG participants during January to August 2009. The authors provided participants with a feedback package containing their practice video (which included verbal feedback) and the completed CaLF tool.The CaLF methodology provides a tool for medical educators and language practitioners to work collaboratively with IMGs to enhance communication and language skills. The ongoing interdisciplinary collaboration also provides much-needed applied research opportunities in intercultural health communication, an area the authors believe cannot be adequately addressed from the perspective of one discipline alone.

To evaluate the apprehensions, social, sexual and financial problems in patients with advanced laryngeal cancer after total laryngectomy and the impact of attending laryngeal club on these problems. The analytical study was conducted at the Dow Medical College and Civil Hospital Karachi from January 1996 to December 2011. Patients with total laryngectomy, operated for advanced laryngeal cancer at various centres of Sindh and Balochistan, attending Laryngeal Club of Pakistan, situated at Civil Hospital Karachi, were included. All the patients were evaluated through a questionnaire covering their apprehensions regarding social, sexual and financial impact on their lives after total laryngectomy. Data was analysed using SPSS 16. Of the 125 patients, 120(96%) were males, and 5(4%) were females; all housewives. The overall mean age was 54.8±0.5 years (range: 31-65 years). Further, 92(74%) participants were worried about financial uncertainty, while 84(67%) had regrets over loss of their voice; patients worried about losing family support and facing social rejection were 23(18%) and 15(12%) respectively. Only 7(5%) patients feared losing sexual relationship with their spouse. All these apprehensions were subdued after attending the Laryngeal Club of Pakistan. Severe financial impact was faced by 55(44%) patients due to loss of job, while 05(4%) had moderate impact due to change of job with lower income and 60(48%) patients had no financial problem. A good 102(82%) participants thought the support from their friends and family was upto their expectations; 98(78%) enjoyed satisfactory sex life although with reduced frequency of 1 to 2 intercourses per month; 21(17%) were having the frequency of 3-10 per month; and 3(2%) had more than 10 per month. Only 16(13%) patients were not involved in sexual relations with their spouses due to various reasons. Majority of laryngectomised patients expressed apprehensions and showed some social problems after laryngectomy, especially in the initial phase which improved either with passage of time or after attending Laryngectomy Club. The main problem was financial constraints; majority had good friends and family support and enjoyed satisfactory sexual relationship with their spouse.

Cognition and Language: From Apprehension to Judgment -- Quantum Conjectures

NASA Astrophysics Data System (ADS)

Arecchi, F. T.

2014-12-01

We critically discuss the two moments of human cognition, namely, apprehension (A), whereby a coherent perception emerges from the recruitment of neuronal groups, and judgment (B), that entails the comparison of two apprehensions acquired at different times, coded in a suitable language and recalled by memory. (B) requires selfconsciousness, in so far as the agent who expresses the judgment must be aware that the two apprehensions are submitted to his/her own scrutiny and that it is his/her duty to extract a mutual relation. Since (B) lasts around 3 seconds, the semantic value of the pieces under comparison must be decided within this time. This implies a fast search of the memory contents. As a fact, exploring human subjects with sequences of simple words, we find evidence of a limited time window, corresponding to the memory retrieval of a linguistic item in order to match it with the next one in a text flow (be it literary, or musical,or figurative). Classifying the information content of spike trains, an uncertainty relation emerges between the bit size of a word and its duration. This uncertainty is ruled by a constant that can be given a numerical value and that has nothing to do with Planck's constant. A "quantum conjecture" in the above sense might explain the onset and decay of the memory window connecting successive pieces of a linguistic text. The conjecture here formulated is applicable to other reported evidences of quantum effects in human cognitive processes, so far lacking a plausible framework since no efforts to assign a quantum constant have been associated.

Origins of the New Latino Underclass.

PubMed

Massey, Douglas S; Pren, Karen A

2012-04-01

Over the past four decades, the Latino population of the United States was transformed from a small, ethnically segmented population of Mexicans in the southwest, Puerto Ricans in New York, and Cubans in Miami into a large national population dominated by Mexicans, Central Americans, and South Americans. This transformation occurred through mass immigration, much of it undocumented, to the point where large fractions of non-Caribbean Hispanics lack legal protections and rights in the United States. Rising illegality is critical to understanding the disadvantaged status of Latinos today. The unauthorized population began to grow after avenues for legal entry were curtailed in 1965. The consequent rise in undocumented migration enabled political and bureaucratic entrepreneurs to frame Latino migration as a grave threat to the nation, leading to a rising frequency of negative framings in the media, a growing conservative reaction, and increasingly restrictive immigration and border policies that generated more apprehensions. Rising apprehensions, in turn, further enflamed the conservative reaction to produce even harsher enforcement and more still more apprehensions, yielding a self-feeding cycle in which apprehensions kept rising even though undocumented inflows had stabilized. The consequent militarization of the border had the perverse effect of reducing rates of out-migration rather than inhibiting in-migration, leading to a sharp rise in net undocumented population and rapid growth of the undocumented population. As a result, a majority of Mexican, Central American, and South American immigrants are presently undocumented at a time when unauthorized migrants are subject to increasing sanctions from authorities and the public, yielding down-ward pressure on the status and well-being of Latinos in the United States.

Worry-inducing stimuli in an aversive Go/NoGo task enhance reactive control in individuals with lower trait-anxiety.

PubMed

Leue, Anja; Rodilla, Carmen Cano; Beauducel, André

2017-04-01

This study relates predictions on reactive and proactive cognitive control to findings on anxious apprehension/worry and ERN/Ne. We investigated whether worry-inducing stimuli in an aversive performance setting lead to a more pronounced increase of the ERN/Ne in individuals with lower anxious apprehension/worry. We also explored the N2 amplitude in the context of worry-inducing stimuli. Fifty-eight participants performed an extended Go/NoGo task. A neutral or fearful face was presented at the beginning of each trial, with the fearful face as a worry-inducing, distracting stimulus. In an aversive feedback condition, aversive feedback was provided for false or too slow responses. We found a more pronounced decrease of the ERN/Ne after worry-inducing stimuli compared to neutral stimuli in participants with lower anxious apprehension/worry. Moreover, less pronounced N2 amplitudes were associated with shorter reaction times in the aversive feedback condition. Implications for future research on error monitoring and trait-anxiety are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

A network consisting of left dorsolateral prefrontal cortex (LDLPFC) and dorsal anterior cingulate cortex (dACC) has been implicated in top-down attentional control. Few studies have systematically investigated how this network is altered in psychopathology, despite evidence that depression and anxiety are associated with attentional control impairments. Functional MRI and dense-array event-related brain potential (ERP) data were collected in separate sessions from 100 participants during a color-word Stroop task. Functional MRI results guided ERP source modeling to characterize the time course of activity in LDLPFC (300-440 ms) and dACC (520-680 ms). At low levels of depression, LDLPFC activity was indirectly related to Stroop interference and only via dACC activity. In contrast, at high levels of depression, dACC did not play an intervening role, and increased LDLPFC activity was directly related to decreased Stroop interference. Specific to high levels of anxious apprehension, higher dACC activity was related to more Stroop interference. Results indicate that depression and anxious apprehension modulate temporally and functionally distinct aspects of the frontocingulate network involved in top-down attention control.

Web-based training is frequently used by organizations as a convenient and low-cost way to teach employees new knowledge and skills. As web-based training is typically unproctored, employees may be held accountable to the organization by computer software that monitors their behaviors. The current study examines how the introduction of electronic performance monitoring may provoke negative emotional reactions and decrease learning among certain types of e-learners. Through motivated action theory and trait activation theory, we examine the role of performance goal orientation when e-learners are exposed to asynchronous and synchronous monitoring. We show that some e-learners are more susceptible than others to evaluation apprehension when they perceive their activities are being monitored electronically. Specifically, e-learners higher in avoid performance goal orientation exhibited increased evaluation apprehension if they believed asynchronous monitoring was present, and they showed decreased skill attainment as a result. E-learners higher on prove performance goal orientation showed greater evaluation apprehension if they believed real-time monitoring was occurring, resulting in decreased skill attainment.

Vivisecting Major: a Victorian gentleman scientist defends animal experimentation, 1876-1885.

PubMed

Boddice, Rob

2011-06-01

Through an investigation of the public, professional, and private life of the Darwinian disciple George John Romanes, this essay seeks a better understanding of the scientific motivations for defending the practice of vivisection at the height of the controversy in late Victorian Britain. Setting aside a historiography that has tended to focus on the arguments of antivivisectionists, it reconstructs the viewpoint of the scientific community through an examination of Romanes's work to help orchestrate the defense of animal experimentation. By embedding his life in three complicatedly overlapping networks-the world of print, interpersonal communications among an increasingly professionalized body of scientific men, and the intimacies of private life-the essay uses Romanes as a lens with which to focus the physiological apprehension of the antivivisection movement. It is a story of reputation, self-interest, and affection.

Prostate cancer (PrCA) is the most commonly diagnosed nonskin cancer among men. African American (AA) men in South Carolina have a PrCA death rate 150% higher than that of European American (EA) men. This in-depth qualitative research explored AA men's and women's current practices, barriers, and recommended strategies for PrCA communication. A purposive sample of 43 AA men and 38 AA spouses/female relatives participated in focus groups (11 male groups; 11 female groups). A 19-item discussion guide was developed. Coding and analyses were driven by the data; recurrent themes within and across groups were examined. Findings revealed AA men and women agreed on key barriers to discussing PrCA; however, they had differing perspectives on which of these were most important. Findings indicate that including AA women in PrCA research and education is needed to address barriers preventing AA men from effectively communicating about PrCA risk and screening with family and health care providers.

2003-01-01

A novel cadaveric model for anterior-inferior shoulder dislocation using forcible apprehension positioning is presented. This model simulates an in vivo mechanism and yields capsulolabral lesions. The scapulae of 14 cadaveric entire upper limbs (82 +/- 9 years, mean +/- standard deviation) were each rigidly fixed to a custom shoulder-testing device. A pneumatic system was used with pulleys and cables to simulate the rotator cuff and the deltoid muscles (anterior and middle portions). The glenohumeral joint was then positioned in the apprehension position of abduction, external rotation, and horizontal abduction. A 6-degree-of-freedom load cell (Assurance Technologies, Garner, North Carolina) measured the joint reaction force that was then resolved into three orthogonal components of compression force, anteriorly directed force, and superiorly directed force. With the use of a thrust bearing, the humerus was moved along a rail with a servomotor-controlled system at 50 mm/s that resulted in horizontal abduction. Force that developed passively in the pectoralis major muscle was recorded with an independent uniaxial load cell. Each of the glenohumeral joints dislocated anterior-inferior, six with avulsion of the capsulolabrum from the anterior-inferior glenoid bone and eight with capsulolabral stretching. Pectoralis major muscle force as well as the joint reaction force increased with horizontal abduction until dislocation. At dislocation, the magnitude of the pectoralis major muscle force, 609.6 N +/- 65.2 N was similar to the compression force, 569.6 N +/- 37.8 N. A cadaveric model yielded an anterior dislocation with a mechanism of forcible apprehension positioning when the appropriate shoulder muscles were simulated and a passive pectoralis major muscle was included. Capsulolabral lesions resulted, similar to those observed in vivo.

The primary aim of this study was to explore changes in knowledge level, perceived importance and apprehension of immunizations by first year pharmacy students pre- vs. post-immunization education and training. First year pharmacy students at the University of California San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences (UC San Diego SSPPS) completed a pre- and post-immunization training course questionnaire. Knowledge base and perceived importance level of immunizations including hepatitis B, influenza, measles, mumps, rubella (MMR), varicella, tetanus, diphtheria, pertussis (Tdap), meningococcal and human papilloma virus (HPV) were assessed. In addition, apprehension of needle administration and fears regarding safety and efficacy were evaluated. Of 120 students, 85 (71%) completed pre- and post-course questionnaires for this study. Mean knowledge test scores increased from 56% pre-course to 83% post-course. Pre-course, 73% of participants considered immunizations as very important in preventing future disease outbreaks. Post-course, this percentage climbed to 94%. Prior to taking the course, 52% of students were apprehensive about administering injections; however, after completing the course this percentage declined to 33%. The majority of students who had been fearful prior to the course retained their fears of receiving needle injections. The proportion of students believing immunizations should be a personal choice, not mandatory, did not significantly change from pre-course (49%) to post-course (44%). The UC San Diego SSPPS immunization course increased student knowledge of immunization facts and the perceived importance of immunizations. However, a substantial portion of students retained apprehension about administering and receiving needle injections and the proportion believing immunizations should be a personal choice, almost half, did not change appreciably.

Children diagnosed with neurodevelopmental conditions such as cerebral palsy (CP) are at risk of experiencing restrictions in social activities negatively impacting their subsequent social functioning. Research has identified motor and communication ability as being unique determinants of social function capabilities in children with CP, to date, no research has investigated whether communication is a mediator of the relationship between motor ability and social functioning. To investigate whether early communication ability at 24 months corrected age (ca.) mediates the relationship between early motor ability at 24 months ca. and later social development at 60 months ca. in a cohort of children diagnosed with cerebral palsy (CP). A cohort of 71 children (43 male) diagnosed with CP (GMFCS I=24, 33.8%, II=9, 12.7%, III=12, 16.9%, IV=10, 14.1%, V=16, 22.5%) were assessed at 24 and 60 months ca. Assessments included the Gross Motor Function Measure (GMFM), the Communication and Symbolic Behaviour Scales-Developmental Profile (CSBS-DP) Infant-Toddler Checklist and the Paediatric Evaluation of Disability Inventory (PEDI). A mediation model was examined using bootstrapping. Early communication skills mediated the relationship between early motor abilities and later social functioning, b=0.24 (95% CI=0.08-0.43 and the mediation model was significant, F (2, 68)=32.77, p<0.001, R(2)=0.49. Early communication ability partially mediates the relationship between early motor ability and later social function in children with CP. This demonstrates the important role of early communication in ongoing social development. Early identification of communication delay and enriched language exposure is crucial in this population.

2008-06-01

The automation of DNA profile analysis of reference and crime samples continues to gain pace driven in part by a realisation by the criminal justice system of the positive impact DNA technology can have in aiding in the solution of crime and the apprehension of suspects. Expert systems to automate the profile analysis component of the process are beginning to be developed. In this paper, we report the validation of a new expert system FaSTR DNA, an expert system suitable for the analysis of DNA profiles from single source reference samples and from crime samples. We compare the performance of FaSTR DNA with that of other equivalent systems, GeneMapper ID v3.2 (Applied Biosystems, Foster City, CA) and FSS-i(3) v4 (The Forensic Science Service((R)) DNA expert System Suite FSS-i(3), Forensic Science Service, Birmingham, UK) with GeneScan Analysis v3.7/Genotyper v3.7 software (Applied Biosystems, Foster City, CA, USA) with manual review. We have shown that FaSTR DNA provides an alternative solution to automating DNA profile analysis and is appropriate for implementation into forensic laboratories. The FaSTR DNA system was demonstrated to be comparable in performance to that of GeneMapper ID v3.2 and superior to that of FSS-i(3) v4 for the analysis of DNA profiles from crime samples.

Clinical waste incinerators in Cameroon--a case study.

PubMed

Mochungong, Peter Ikome Kuwoh; Gulis, Gabriel; Sodemann, Morten

2012-01-01

Incinerators are widely used to treat clinical waste in Cameroon's Northwest Region. These incinerators cause public apprehension owing to purported risks to operators, communities and the environment. This article aims to summarize findings from an April 2008 case study. Three incinerators were randomly selected and investigated for site, design and operating standards. Empirical field observation was adopted and data collected through inventory and informal interviews. Bottom ash samples collected from the incinerators were prepared according to standard procedures and analyzed for heavy metals using Inductively Coupled Plasma (ICP) Emission Spectroscopy. Shortcomings associated with site selection, design and operation standards were identified. Chemical analysis revealed that Cr, Cu, Fe, Mn, Ni, Pb, Zn, Mg and Ca were present in the bottom ash with mean concentration ranging from 10 mg/kg for Pb to 178080 mg/kg for Ca. For logistic reasons, feedstock quantity and quality into the incinerators were not investigated. Neither were soil samples around and away from the incinerators. Although highly favored, clinical waste incineration methods in this region have to be reconsidered. A thorough health and environmental impact assessment is suggested before subsequent decisions on choice and disposal site is made. This will curb potential negative impacts to the environment and public health. This article adds a different perspective and sheds additional information to the debate on unsatisfactory clinical waste incinerators in resources-poor countries. Alternative methods to incineration are presented that will be helpful to practitioners.

Physically disconnected non-diffusible cell-to-cell communication between neuroblastoma SH-SY5Y and DRG primary sensory neurons.

2013-01-01

Cell-cell communication occurs via a variety of mechanisms, including long distances (hormonal), short distances (paracrine and synaptic) or direct coupling via gap junctions, antigen presentation, or ligand-receptor interactions. We evaluated the possibility of neuro-hormonal independent, non-diffusible, physically disconnected pathways for cell-cell communication using dorsal root ganglion (DRG) neurons. We assessed intracellular calcium ([Ca(2+)]) in primary culture DRG neurons that express ATP-sensitive P2X3, capsaicinsensitive TRPV1 receptors modulated by estradiol. Physically disconnected (dish-in-dish system; inner chamber enclosed) mouse DRG were cultured for 12 hours near: a) media alone (control 1), b) mouse DRG (control 2), c) human neuroblastoma SHSY-5Y cells (cancer intervention), or d) mouse DRG treated with KCl (apoptosis intervention). Chemosensitive receptors [Ca(2+)](i) signaling did not differ between control 1 and 2. ATP (10 μM) and capsaicin (100nM) increased [Ca(2+)](i) transients to 425.86 + 49.5 nM, and 399.21 ± 44.5 nM, respectively. 17β-estradiol (100 nM) exposure reduced ATP (171.17 ± 48.9 nM) and capsaicin (175.01±34.8 nM) [Ca(2+)](i) transients. The presence of cancer cells reduced ATP- and capsaicin-induced [Ca(2+)](i) by >50% (p<0.05) and abolished the 17β-estradiol effect. By contrast, apoptotic DRG cells increased initial ATP-induced [Ca(2+)](i), flux four fold and abolished subsequent [Ca(2+)](i), responses to ATP stimulation (p<0.001). Capsaicin (100nM) induced [Ca(2+)](i) responses were totally abolished. The local presence of apoptotic DRG or human neuroblastoma cells induced differing abnormal ATP and capsaicin-mediated [Ca(2+)](i) fluxes in normal DRG. These findings support physically disconnected, non-diffusible cell-to-cell signaling. Further studies are needed to delineate the mechanism(s) of and model(s) of communication.

Intercellular signal communication among odontoblasts and trigeminal ganglion neurons via glutamate.

Various stimuli to the exposed surface of dentin induce changes in the hydrodynamic force inside the dentinal tubules resulting in dentinal pain. Recent evidences indicate that mechano-sensor channels, such as the transient receptor potential channels, in odontoblasts receive these hydrodynamic forces and trigger the release of ATP to the pulpal neurons, to generate dentinal pain. A recent study, however, has shown that odontoblasts also express glutamate receptors (GluRs). This implies that cells in the dental pulp tissue have the ability to release glutamate, which acts as a functional intercellular mediator to establish inter-odontoblast and odontoblast-trigeminal ganglion (TG) neuron signal communication. To investigate the intercellular signal communication, we applied mechanical stimulation to odontoblasts and measured the intracellular free Ca 2+ concentration ([Ca 2+ ] i ). During mechanical stimulation in the presence of extracellular Ca 2+ , we observed a transient [Ca 2+ ] i increase not only in single stimulated odontoblasts, but also in adjacent odontoblasts. We could not observe these responses in the absence of extracellular Ca 2+ . [Ca 2+ ] i increases in the neighboring odontoblasts during mechanical stimulation of single odontoblasts were inhibited by antagonists of metabotropic glutamate receptors (mGluRs) as well as glutamate-permeable anion channels. In the odontoblast-TG neuron coculture, we observed an increase in [Ca 2+ ] i in the stimulated odontoblasts and TG neurons, in response to direct mechanical stimulation of single odontoblasts. These [Ca 2+ ] i increases in the neighboring TG neurons were inhibited by antagonists for mGluRs. The [Ca 2+ ] i increases in the stimulated odontoblasts were also inhibited by mGluRs antagonists. We further confirmed that the odontoblasts express group I, II, and III mGluRs. However, we could not record any currents evoked from odontoblasts near the mechanically stimulated odontoblast, with or without extracellular Mg 2+ , indicating that N-methyl-d-aspartic acid receptor does not contribute to inter-odontoblast signal communication. The results suggest that a mechanically stimulated odontoblast is capable of releasing glutamate into the extracellular space via glutamate-permeable anion channels. The released glutamate activates mGluRs on the odontoblasts in an autocrine/paracrine manner, forming an inter-odontoblasts communication, which drives dentin formation via odontoblast-odontoblast signal communication. Glutamate and mGluRs also mediate neurotransmission between the odontoblasts and neurons in the dental pulp to modulate sensory signal transmission for dentinal sensitivity.

Evolutionary and functional perspectives on signaling from neuronal surface to nucleus

Reliance on Ca{sup 2+} signaling has been well-preserved through the course of evolution. While the complexity of Ca{sup 2+} signaling pathways has increased, activation of transcription factors including CREB by Ca{sup 2+}/CaM-dependent kinases (CaMKs) has remained critical for long-term plasticity. In C. elegans, the CaMK family is made up of only three members, and CREB phosphorylation is mediated by CMK-1, the homologue of CaMKI. CMK-1 nuclear translocation directly regulates adaptation of thermotaxis behavior in response to changes in the environment. In mammals, the CaMK family has been expanded from three to ten members, enabling specialization of individual elements of amore » signal transduction pathway and increased reliance on the CaMKII subfamily. This increased complexity enables private line communication between Ca{sup 2+} sources at the cell surface and specific cellular targets. Using both new and previously published data, we review the mechanism of a γCaMKII-CaM nuclear translocation. This intricate pathway depends on a specific role for multiple Ca{sup 2+}/CaM-dependent kinases and phosphatases: α/βCaMKII phosphorylates γCaMKII to trap CaM; CaN dephosphorylates γCaMKII to dispatch it to the nucleus; and PP2A induces CaM release from γCaMKII so that CaMKK and CaMKIV can trigger CREB phosphorylation. Thus, while certain basic elements have been conserved from C. elegans, evolutionary modifications offer opportunities for targeted communication, regulation of key nodes and checkpoints, and greater specificity and flexibility in signaling.« less

Defining the pathways through which neurons and astrocytes communicate may contribute to the elucidation of higher central nervous system functions. We investigated the possibility that decreases in extracellular calcium ion concentration ([Ca(2+)](e)) that occur during synaptic transmission might mediate signaling from neurons to glia. Using noninvasive photolysis of the photolabile Ca(2+) buffer diazo-2 {N-[2-[2-[2-[bis(carboxymethyl)amino]-5-(diazoacetyl)phenoxy]ethoxy]-4-methylphenyl]-N-(carboxymethyl)-, tetrapotassium salt} to reduce [Ca(2+)](e) or caged glutamate to simulate glutamatergic transmission, we found that a local decline in extracellular Ca(2+) triggered astrocytic adenosine triphosphate (ATP) release and astrocytic Ca(2+) signaling. In turn, activation of purinergic P2Y1 receptors on a subset of inhibitory interneurons initiated the generation of action potentials by these interneurons, thereby enhancing synaptic inhibition. Thus, astrocytic ATP release evoked by an activity-associated decrease in [Ca(2+)](e) may provide a negative feedback mechanism that potentiates inhibitory transmission in response to local hyperexcitability.

Signal percolation through plants and the shape of the calcium signature.

PubMed

Plieth, Christoph

2010-04-01

Plants respond to almost any kind of external stimulus with transients in their cytoplasmic free calcium concentration ([Ca(2+)](c)). A huge variety of kinetics recorded by optical techniques has been reported in the past. This variety has been credited the specificity needed to explain how information about incoming stimuli is evaluated by the organism and turned into the right physiological responses which provide advantages for survival and reproduction. A physiological response often takes place away from the site of stimulation. This requires cell-to-cell communication. Hence, responding cells are not necessarily directly stimulated but rather receive an indirect stimulus via cell-to-cell communication. It appears unlikely that the '[Ca(2+)](c) signature' in the primarily stimulated cell is conveyed over long distances via cell-to-cell communication from the 'receptor cells' to the 'effector cells'. Here, a novel aspect is highlighted to explain the variety of [Ca(2+)] kinetics seen by integrating methods of [Ca(2+)](c) recording. Plants can generally be seen as cellular automata with specific morphology and capable for cell-to-cell communication. Just a few rules are needed to demonstrate how waves of [Ca(2+)](c)-increases percolate through the organism and thereby deliver a broad variety of 'signatures'. Modelling intercellular signalling may be a possible way to find explanations for different kinds of signal transmission, signal amplification, wave formation, oscillations and stimulus-response coupling. The basic examples presented here show that care has to be taken when interpreting cellular '[Ca(2+)](c) signatures' recorded by optical techniques which integrate over a big number of cells or even whole plants.

Brainstorming groups have consistently produced fewer ideas than have the equivalent number of individuals working by themselves. These results have been attributed to social loafing, evaluation apprehension, and production blocking in groups. In this study, a new brainstorming technique--electronic brainstorming--that may reduce both production blocking and evaluation apprehension was assessed. Electronic and nonelectronic groups and nominal and interacting groups were compared in a 2 x 2 factorial design. Electronic groups were more productive than nonelectronic groups, but the productivity of nominal and interacting groups did not differ. In contrast, interacting groups felt better about the idea-generation process than did nominal groups. Ways in which electronic brainstorming can reopen a long dormant area of research and application are discussed.

Neural evidence for reduced apprehensiveness of familiarized stimuli in a mere exposure paradigm.

PubMed

Zebrowitz, Leslie A; Zhang, Yi

2012-07-01

Mere familiarization with a stimulus increases liking for it or similar stimuli ("mere exposure" effects) as well as perceptual fluency, indexed by the speed and accuracy of categorizing it or similar stimuli ("priming" effects). Candidate mechanisms proposed to explain mere exposure effects include both increased positive affect associated with greater perceptual fluency, and reduced negative affect associated with diminished apprehensiveness of novel stimuli. Although these two mechanisms are not mutually exclusive, it is difficult for behavioral measures to disentangle them, since increased liking or other indices of greater positive affect toward exposed stimuli could result from increases in positive feelings or decreases in negative feelings or both. The present study sought to clarify this issue by building on research showing a dissociation at the neural level in which the lateral orbitofrontal cortex (LOFC) is activated more by negatively valenced than by neutral or positively valenced stimuli, with the reverse effect for medial orbitofrontal cortex (MOFC). Supporting the reduced apprehensiveness hypothesis, we found lower LOFC activation to familiarized faces and objects (repetition suppression). We did not find evidence to support the positive affect hypothesis in increased activation to familiarized stimuli in MOFC or in other parts of the reward circuit that respond more to positively valenced stimuli (repetition enhancement), although enhancement effects were shown in some regions.

Evaluation of aggression in Australian after-hours doctor home-visit services.

Ifediora, Chris O

2018-04-01

Minimizing the risks and distress arising from aggression in after-hours house call (AHHC) services will help improve service quality in the industry. Unfortunately, no national study has ever evaluated this in Australian AHHCs. Apart from reducing this gap, findings from this work will have global relevance given the rising popularity of the AHHC industry worldwide. A survey of all 300 doctors employed by the National Home Doctor Service, Australia's largest AHHC service provider. A validated electronic questionnaire was used to examine the doctors' experiences over a 12-month period. There were 168 valid responses (56% response rate). Aggression prevalence was 47.1%, and just over half (51.8%) of the cases came from the patients. "Verbal aggression" was the commonest (48.3%). Others are "threats" (26.6%), "vexatious complaints" (13.3%), "property damage" (4.2%), "physical violence" (4.2%), "sexual harassment" (2.8%), and "stalking" (0.7%). Majority of the respondents were concerned (90.2%) and apprehensive (75.2%) regarding the risks. Doctors who have experienced aggression were more likely to express apprehension (OR = 3.99; CI = 1.54-10.31; P = 0.004), while those that have attained Postgraduate Fellowships (Vocationally Registered) were less likely to report experiences of aggression (OR = 0.28; CI = 0.09-0.84; P = 0.02). Even though a higher proportion of females were concerned (92.3% vs 89.6%) and apprehensive (82.1% vs 73.6%) compared with males, these differences were not statistically significant (Fisher's Exact Tests: P = 1.000 and 0.469, respectively). Aggression in Australian AHHC affects nearly 1-in-2 practitioners, with high levels of concern and apprehension being expressed. Concerned companies should do more to ensure that their doctors attain PG fellowships, as this is linked to lower reports of aggression. Where possible, family and friends need to be involved in patient care, as nearly half of the reported aggressions come from them. © 2017 John Wiley & Sons, Ltd.

Calcium imaging shows differential sensitivity to cooling and communication in luminous transgenic plants.

PubMed

Campbell, A K; Trewavas, A J; Knight, M R

1996-03-01

Imaging of a recombinant bioluminescent Ca2+ indicator, aequorin, in an entire organism showed three novel features of Ca2+ signals in plants. First, cooling the plant from 25 degrees C to 2 degrees C demonstrated differential sensitivities between organs, the roots firing a Ca2+ signal at some 8-10 degrees C higher than the cotyledons. Secondly, prolonged cooling provoked Ca2+ oscillations, but only in the cotyledons. These oscillations occurred with a frequency of 100 s and damped down within 800 s. Thirdly, cooling the roots of mature plants triggered a Ca2+ signal in the leaves, as a result of organ-organ communication. However, warming and then recooling the roots did not generate a second Ca2+ signal in these leaves. This desensitisation was not due to down-regulation in the leaf since this was able to generate a Ca2+ signal of its own when cooled directly. Thus a combination of a recombinant bioluminescent indicator with photon counting imaging reveals startling new aspects of signalling in intact organs and whole organisms.

At the beginning of 2015, sixty-two capsules containing red-brown crystals seized in a historical city in Brazil were sent to this forensic laboratory for drug testing analysis. The material was identified as being Brephedrone, a new psychoactive substance and a bromine synthetic cathinone that is related to serotonin transportation. This substance was analyzed by ATR-FTIR, GC-MS, LC-MS, 1 H, 13 C and 2D NMR. Brephedrone apprehensions have been previously reported in Finland, France and Spain. It was the first detection of this substance in the State of Minas Gerais. No reports or information regarding any other apprehension nor identification of Brephedrone in Brazil were known prior to the present case. Copyright © 2017 Elsevier B.V. All rights reserved.

2014-11-01

In this paper we develop a novel practical application, which give scalable services to the end users when abnormal actives are happening. Architecture of the application has been presented consisting of network infrared cameras and a communication module. In this intelligent surveillance system we use Kinect sensors as the input cameras. Kinect is an infrared laser camera which its user can access the raw infrared sensor stream. We install several Kinect sensors in one room to track the human skeletons. Each sensor returns the body positions with 15 coordinates in its own coordinate system. We use calibration algorithms to calibrate all the body positions points into one unified coordinate system. With the body positions points, we can infer the surveillance context. Furthermore, the messages from the metadata index matrix will be sent to mobile phone through communication module. User will instantly be aware of an abnormal case happened in the room without having to check the website. In conclusion, theoretical analysis and experimental results in this paper show that the proposed system is reasonable and efficient. And the application method introduced in this paper is not only to discourage the criminals and assist police in the apprehension of suspects, but also can enabled the end-users monitor the indoor environments anywhere and anytime by their phones.

Nonlinear Gap Junctions Enable Long-Distance Propagation of Pulsating Calcium Waves in Astrocyte Networks

2010-01-01

A new paradigm has recently emerged in brain science whereby communications between glial cells and neuron-glia interactions should be considered together with neurons and their networks to understand higher brain functions. In particular, astrocytes, the main type of glial cells in the cortex, have been shown to communicate with neurons and with each other. They are thought to form a gap-junction-coupled syncytium supporting cell-cell communication via propagating Ca2+ waves. An identified mode of propagation is based on cytoplasm-to-cytoplasm transport of inositol trisphosphate (IP3) through gap junctions that locally trigger Ca2+ pulses via IP3-dependent Ca2+-induced Ca2+ release. It is, however, currently unknown whether this intracellular route is able to support the propagation of long-distance regenerative Ca2+ waves or is restricted to short-distance signaling. Furthermore, the influence of the intracellular signaling dynamics on intercellular propagation remains to be understood. In this work, we propose a model of the gap-junctional route for intercellular Ca2+ wave propagation in astrocytes. Our model yields two major predictions. First, we show that long-distance regenerative signaling requires nonlinear coupling in the gap junctions. Second, we show that even with nonlinear gap junctions, long-distance regenerative signaling is favored when the internal Ca2+ dynamics implements frequency modulation-encoding oscillations with pulsating dynamics, while amplitude modulation-encoding dynamics tends to restrict the propagation range. As a result, spatially heterogeneous molecular properties and/or weak couplings are shown to give rise to rich spatiotemporal dynamics that support complex propagation behaviors. These results shed new light on the mechanisms implicated in the propagation of Ca2+ waves across astrocytes and the precise conditions under which glial cells may participate in information processing in the brain.

Low- and middle-income countries are striving towards universal health coverage in a variety of ways. Achieving this goal requires the participation of both public and the private sector providers. The study sought to assess existing capacity for independent general practitioner contracting in primary care, the reasons for the low uptake of government national contract and the expectations of general practitioners of such contractual arrangements. This was a case study conducted in a rural district of South Africa. The study employed both quantitative and qualitative data collection methods. Data were collected using a general practitioner and practice profiling tool, and a structured questionnaire. A total of 42 general practitioners were interviewed and their practices profiled. Contrary to observed low uptake of the national general practitioner contract, 90% of private doctors who had not yet subscribed to it were actually interested in it. Substantial evidence indicated that private doctors had the capacity to deliver quality care to public patients. However, low uptake of national contarct related mostly to lack of effective communication and consultation between them and national government which created mistrust and apprehension amongst local private doctors. Paradoxically, these general practitioners expressed satisfaction with other existing state contracts. An analysis of the national contract showed that there were likely to benefit more from it given the relatively higher payment rates and the guaranteed nature of this income. Proposed key requisites to enhanced uptake of the national contract related to the type of the contract, payment arrangements and flexibility of the work regime, and prospects for continuous training and clinical improvements. Low uptake of the national General Practitioner contract was due to variety of factors related to lack of understanding of contract details. Such misunderstandings between potential contracting parties created mistrust and apprehension, which are fundamental antitheses of any effective contractual arrangement. The idea of a one-size-fits-all contract was probably inappropriate. PMID:28299145

Shoulder apprehension is more complex than a pure mechanical problem of the shoulder, creating a scar at the brain level that prevents the performance of specific movements. Surgery corrects for shoulder instability at the physical level, but a re-dislocation within the first year is rather common. Predicting which patient will be likely to have re-dislocation is therefore crucial. We hypothesized that the assessment of neural activity at baseline and follow-up is the key factor to predict the post-operatory outcome. 13 patients with shoulder apprehension (30.03 ± 7.64 years) underwent clinical and fMRI examination before and one year after surgery for shoulder dislocation contrasting apprehension cue videos and control videos. Data analyses included task-related general linear model (GLM) and correlations imaging results with clinical scores. Clinical examination showed decreased pain and increased shoulder functions for post-op vs. pre-op. Coherently, GLM results show decreased activation of the left pre-motor cortex for post-surgery vs. pre-surgery. Right-frontal pole and right-occipital cortex activity predicts good recovery of shoulder function measured by STT. Our findings demonstrate that beside physical changes, changes at the brain level also occur one year after surgery. In particular, decreased activity in pre-motor and orbito-frontal cortex is key factor for a successful post-operatory outcome.

To evaluate the usefulness and outcomes of hypnosis associated with local anesthesia during inguinal hernia repair procedure, notably on post-operative pain. A prospective study included patients operated on inguinal hernia repair according to Lichtenstein technique from January 2013 to September 2014. The cohort was divided into three groups (group 1: local anesthesia; group 2: hypnosis and local anesthesia; and group 3: general anesthesia). A questionnaire was filled by each participant before and after surgery. Pre-operative apprehension, pain at hospital discharge, surgeon comfort during procedure, immediate satisfaction after hospital discharge, and satisfaction at 1 month after surgery were evaluated. A total of 103 patients were included in this study (group 1: n = 55; group 2: n = 35; and group 3: n = 13). Pre-operative apprehension and pain at hospital discharge's scores were significantly higher in the group 3 than in the groups 1 and 2 (p < 0.001). Pain at hospital discharge was significantly lower in the group 2 than in the group 1 (p = 0.03). Pre-operative apprehension, surgeon comfort during procedure, immediate satisfaction after hospital discharge, and satisfaction at 1 month after surgery were similar between groups 1 and 2. Hypnosis combined with local anesthesia is a feasible technique which allows extending inguinal hernia repair to a large population. There is no complication associated with its use.

Neural Evidence for Reduced Apprehensiveness of Familiarized Stimuli in a Mere Exposure Paradigm

Objective. To assess the impact of an audience response system (ARS) on student engagement at a multi-campus college of pharmacy. Methods. An online questionnaire was designed and administered to measure the impact of an ARS on student engagement, distance education, projected use, and satisfaction among pharmacy students for a course delivered across 3 sites via synchronous video transmission. Results. Students reported that use of the ARS made it easier to participate (85.3%) and helped them to focus (75.7%) in classes when the lecturer was physically at a different site. They also valued that the ARS allowed them to respond anonymously (93.2%). A minority of students indicated that use of the ARS was distracting (11.8%). Conclusions. Implementation of an ARS was associated with positive student perceptions of engagement and may improve feelings of connectedness among students at schools with multiple sites. Use of ARSs could also represent a cognitive intercession strategy to help reduce communication apprehension. PMID:22412205

Anxiety is characterized by cognitive biases, including attentional bias to emotional (especially threatening) stimuli. Accounts differ on the time course of attention to threat, but the literature generally confounds emotional valence and arousal and overlooks gender effects, both addressed in the present study. Nonpatients high in self-reported anxious apprehension, anxious arousal, or neither completed an emotion-word Stroop task during ERP recording. Hypotheses differentiated time course of preferential attention to emotional stimuli. Individuals high in anxious apprehension and anxious arousal showed distinct early ERP evidence of preferential processing of emotionally arousing stimuli along with some evidence for gender differences in processing. Healthy controls showed gender differences at both early and later processing stages. The conjunction of valence, arousal, and gender is critical in the time course of attentional bias.

This study explored how culture shapes relationships in aged care and the extent to which the residential aged care sector supports a cohesive multicultural workforce. An exploratory methodology utilising semi-structured questionnaires collected data from 58 participants comprising: staff who provide direct care to residents; managers; and family members from six residential care facilities in Perth, Western Australia. Communication issues emerged as an over-arching theme, and included interpersonal communication, the effect of cultural norms on communication and the impact of informal and formal workplace policies relating to spoken and written language. Sixty percent of participants from a culturally and linguistically diverse (CaLD) background had experienced negative reactions from residents with dementia, linked to visible cultural difference. They used a range of coping strategies including ignoring, resilience and avoidance in such situations. CaLD participants also reported prejudicial treatment from non-CaLD staff. The findings highlight the need for organisations to incorporate explicit processes which address the multiple layers of influence on cross cultural communication: internalised beliefs and values; moderating effects of education, experience and social circumstance; and factors external to the individuals, including workplace culture and the broader political economy, to develop a cohesive multicultural workplace.

To examine the results of simulation-based education with deliberate practice on the acquisition of handoff skills by studying resident intraoperative handoff communication performances. Preinvention and postintervention pilot study. Simulated operating room of a university-affiliated hospital. Resident handoff performances during 27 encounters simulating elective surgery were studied. Ten residents (CA-1, CA-2, and CA-3) participated in a one-day simulation-based handoff course. Each resident repeated simulated handoffs to deliberately practice with an intraoperative handoff checklist. One year later, 7 of the 10 residents participated in simulated intraoperative handoffs. All handoffs were videotaped and later scored for accuracy by trained raters. A handoff assessment tool was used to characterize the type and frequency of communication failures. The percentage of handoff errors and omissions were compared before simulation and postsimulation-based education with deliberate practice and at one year following the course. Initially, the overall communication failure rate, defined as the percentage of handoff omissions plus errors, was 29.7%. After deliberate practice with the intraoperative handoff checklist, the communication failure rate decreased to 16.8%, and decreased further to 13.2% one year after the course. Simulation-based education using deliberate practice may result in improved intraoperative handoff communication and retention of skills at one year. Copyright © 2014 Elsevier Inc.

To determine the perception of Primary Care (PC) physicians on the integration with cardiology (CA) through continuity of healthcare programs. A cross-sectional and multicentre study was conducted, in which a total of 200 PC physicians from all over Spain completed a qualitative survey that evaluated the level of integration with CA in secondary prevention. Physicians were grouped according to the level of PC-CA integration. The integration between CA and PC was good, but it was better in those centres with a higher integration (74.0% vs. 60.0%; p=.02) and in general, physicians considered that integration had improved (92.0% vs. 73.0%; p<.001). Almost all PC physicians received the hospital discharge report. The majority of the hospital discharge reports included recommendations about the CA and PC follow-up, control of risk factors, as well as the duration of secondary prevention treatment, with not significant differences according to the level of integration. In 55.8%, 63.6%, and 51.3% of hospital discharge reports, indications were given on when to perform the follow-up blood analysis, as well as information about returning to working life and sexual activity, respectively. The most common communication method was the paper-based report (75 vs. 84%; p=NS). The communication between healthcare levels was greater in those Primary Care centres with a higher level of integration, as well as periodicity of the communication and the satisfaction of physicians (80.0% vs. 63.0%; p=.005). The level of integration between PC and CA is, in general, satisfactory, but those centres with a higher level of integration benefit more from a greater communication and satisfaction.

The purpose of this in vitro biomechanical study was to assess the effects of the remplissage procedure for small- and large-sized Hill-Sachs lesions (HSLs) on shoulder range of motion (ROM) with a special interest in the apprehension position. HSLs of 50% and 100% of the glenoid width were simulated in 7 cadaveric shoulders as small and large lesions, respectively, and the postoperative condition was reproduced by placing suture anchors on the articular surface and tying down the infraspinatus at the medial edge of the would-be lesion site. ROMs were measured in abduction, internal rotation, and external rotation with the humerus in the adducted and abducted position. In addition, the ROM was measured in the anterior apprehension position, in which 2 torques of external rotation and extension were applied simultaneously, and external rotation and horizontal extension ROMs were measured with the humerus in different abduction angles (20°, 40°, and 60°). For standard ROMs, the procedure for the 50% HSL maintained complete ROMs, whereas the procedure for the 100% HSL significantly decreased external rotation ROM with the humerus in both the adducted and abducted positions, as well as abduction ROM. In the apprehension position, remplissage for the 50% HSL decreased extension ROM with the humerus abducted to 40° and 60°. Remplissage for the 100% HSL significantly decreased both external and extension ROMs regardless of the humeral abduction angle. In the cadaveric model with an intact humeral head and the simulated postoperative condition, the remplissage procedure for a large HSL caused significant restrictions in ROM of abduction in the scapular plane and external rotation with the humerus in both adduction and abduction. It also caused significant restrictions in both external rotation and extension ROMs in the apprehension position. The indication for the remplissage procedure for the larger HSL should be considered carefully, especially for the competitive throwing athlete who needs exceptional external rotation ROM for optimal overhead throwing performance.

Gap junctions and other mechanisms of cell-cell communication regulate basal insulin secretion in the pancreatic islet.

PubMed

Cell-cell communication in the islet of Langerhans is important for the regulation of insulin secretion. Gap-junctions coordinate oscillations in intracellular free-calcium ([Ca(2+)](i)) and insulin secretion in the islet following elevated glucose. Gap-junctions can also ensure that oscillatory [Ca(2+)](i) ceases when glucose is at a basal levels. We determine the roles of gap-junctions and other cell-cell communication pathways in the suppression of insulin secretion under basal conditions. Metabolic, electrical and insulin secretion levels were measured from islets lacking gap-junction coupling following deletion of connexion36 (Cx36(-/-)), and these results were compared to those obtained using fully isolated β-cells. K(ATP) loss-of-function islets provide a further experimental model to specifically study gap-junction mediated suppression of electrical activity. In isolated β-cells or Cx36(-/-) islets, elevations in [Ca(2+)](i) persisted in a subset of cells even at basal glucose. Isolated β-cells showed elevated insulin secretion at basal glucose; however, insulin secretion from Cx36(-/-) islets was minimally altered. [Ca(2+)](i) was further elevated under basal conditions, but insulin release still suppressed in K(ATP) loss-of-function islets. Forced elevation of cAMP led to PKA-mediated increases in insulin secretion from islets lacking gap-junctions, but not from islets expressing Cx36 gap junctions. We conclude there is a redundancy in how cell-cell communication in the islet suppresses insulin release. Gap junctions suppress cellular heterogeneity and spontaneous [Ca(2+)](i) signals, while other juxtacrine mechanisms, regulated by PKA and glucose, suppress more distal steps in exocytosis. Each mechanism is sufficiently robust to compensate for a loss of the other and still suppress basal insulin secretion.

Computer-assisted system for the reconstruction of shattered objects

NASA Astrophysics Data System (ADS)

Cooper, Frederick A.; Brenningmeyer, Todd

2005-05-01

Reconstruction for forensic purposes of shattered or otherwise damaged objects has been a painstaking, if not impossible, undertaking. The forensic crime scientist and the archaeologist share this challenge. A pilot project, funded by the National Institute of Justice experimented with several avenues of approach to this problem of reassembly by using the 627 fragmented pieces of a pane of glass from a crime scene. I was approached by staff members of the Forensic Laboratory of the Minnesota Bureau of Criminal Apprehension because I was developing a means to restore a Greek Bronze Age wall painting (ca. 1350 B.C.E.) fragmented into 4750 pieces and a Greek temple (ca. 150 B.C.E.) demolished by vandals about 1500 years ago, leaving behind 1485 stone blocks, 1-3 tons each. The challenge was to develop an automated method to rapidly and effectively analyze a quantity of fragments of like kind separated one from the other and from the original object by violence and other means. The project established a set of mathematically and graphically definable characteristics held by the glass sherds which allowed for the making of joins between pieces. Preparation included the formulation of inventory check-sheets and a barcode label system with a unique identifier for each piece based on a x,y,z grid system. The next step involved experimentation with an array of proprietary GIS, SQL, and CAD software alternatives for the processing of data. In the end we settled on maximum likelihood analysis of SQL filtered results. This and shape indices were complied using ArcView and the scripting language, Avenue, products of ESRI, Redlands, California.

2010-03-01

Brain activation associated with anhedonic depression and co-occurring anxious arousal and anxious apprehension was measured by fMRI during performance of an emotion word Stroop task. Consistent with EEG findings, depression was associated with rightward frontal lateralization in the dorsolateral prefrontal cortex (DLPFC), but only when anxious arousal was elevated and anxious apprehension was low. Activity in the right inferior frontal gyrus (IFG) was also reduced for depression under the same conditions. In contrast, depression was associated with more activity in the anterior cingulate cortex (dorsal ACC and rostral ACC) and the bilateral amygdala. Results imply that depression, particularly when accompanied by anxious arousal, may result in a failure to implement top-down processing by appropriate brain regions (left DLPFC, right IFG) due to increased activation in regions associated with responding to emotionally salient information (right DLPFC, amygdala).

Objectives To explore beliefs and apprehensions about disease and its treatment in patients with rheumatoid arthritis and spondyloarthritis. Methods 25 patients with rheumatoid arthritis and 25 with spondyloarthritis participated in semi-structured interviews about their disease and its treatment. The interviews were performed by trained interviewers in participants' homes. The interviews were recorded and the main themes identified by content analysis. Results Patients differentiated between the underlying cause of the disease, which was most frequently identified as a hereditary or individual predisposition. In patients with rheumatoid arthritis, the most frequently cited triggering factor for disease onset was a psychological factor or life-event, whereas patients with spondyloarthritis tended to focus more on an intrinsic vulnerability to disease. Stress and overexertion were considered important triggering factors for exacerbations, and relaxation techniques were frequently cited strategies to manage exacerbations. The unpredictability of the disease course was a common source of anxiety. Beliefs about the disease and apprehensions about the future tended to evolve over the course of the disease, as did treatment expectations. Conclusions Patients with rheumatoid arthritis and spondyloarthritis hold a core set of beliefs and apprehensions that reflect their level of information about their disease and are not necessarily appropriate. The physician can initiate discussion of these beliefs in order to dispel misconceptions, align treatment expectations, provide reassurance to the patient and readjust disease management. Such a dialogue would help improve standards of care in these chronic and incapacitating diseases. PMID:25474157

Most patient education involves passive learning. To improve patient education regarding surgery, an active learning workshop-based teaching method is proposed. The objective of this study was to assess level of patient surgical knowledge, achievement of workshop learning objectives, patient apprehension about future surgery, and participant workshop satisfaction after completing a surgical training workshop. A four-station workshop (surgical scrub, surgical suture, laparoscopic surgery, and robotic surgery) was developed to teach four important components of the surgical process. Healthy, surgery-naive adolescents were enrolled to attend this 1-h workshop-based training program. Training received by participants was technically and procedurally identical to training received by actual surgeons. Pre- and post-workshop questionnaires were used to assess learning outcomes. There were 1312 participants, with a mean age 15.9 ± 1.1 years and a gender breakdown of 303 males and 1009 females. For surgical knowledge, mean pre-workshop and post-workshop scores were 6.1 ± 1.5 and 7.5 ± 1.5 (out of 10 points), respectively (p < 0.001). Out of 5 possible points, achievement of learning objectives, decreased apprehension about future surgery, and overall workshop satisfaction scores were all higher than 4.5. Active, hands-on patient education is an effective way to improve understanding of surgery-related processes. This teaching method may also decrease apprehension that patients or potential patients harbor regarding a future surgical procedure.

Synaptic communication between neurons and NG2+ cells.

PubMed

Paukert, Martin; Bergles, Dwight E

2006-10-01

Chemical synaptic transmission provides the basis for much of the rapid signaling that occurs within neuronal networks. However, recent studies have provided compelling evidence that synapses are not used exclusively for communication between neurons. Physiological and anatomical studies indicate that a distinct class of glia known as NG2(+) cells also forms direct synaptic junctions with both glutamatergic and GABAergic neurons. Glutamatergic signaling can influence intracellular Ca(2+) levels in NG2(+) cells by activating Ca(2+) permeable AMPA receptors, and these inputs can be potentiated through high frequency stimulation. Although the significance of this highly differentiated form of communication remains to be established, these neuro-glia synapses might enable neurons to influence rapidly the behavior of this ubiquitous class of glial progenitors.

Catastrophic misinterpretations as a predictor of symptom change during treatment for panic disorder.

PubMed

Teachman, Bethany A; Marker, Craig D; Clerkin, Elise M

2010-12-01

Cognitive models of panic disorder suggest that change in catastrophic misinterpretations of bodily sensations will predict symptom reduction. To examine change processes, we used a repeated measures design to evaluate whether the trajectory of change in misinterpretations over the course of 12-week cognitive behavior therapy is related to the trajectory of change in a variety of panic-relevant outcomes. Participants had a primary diagnosis of panic disorder (N = 43; 70% female; mean age = 40.14 years). Race or ethnicity was reported as 91% Caucasian, 5% African American, 2.3% biracial, and 2.3% "other." Change in catastrophic misinterpretations (assessed with the Brief Body Sensations Interpretation Questionnaire; Clark et al., 1997) was used to predict a variety of treatment outcomes, including overall panic symptom severity (assessed with the Panic Disorder Severity Scale [PDSS]; Shear et al., 1997), panic attack frequency (assessed with the relevant PDSS item), panic-related distress/apprehension (assessed by a latent factor, including peak anxiety in response to a panic-relevant stressor-a straw breathing task), and avoidance (assessed by a latent factor, which included the Fear Questionnaire-Agoraphobic Avoidance subscale; Marks & Mathews, 1979). Bivariate latent difference score modeling indicated that, as expected, change in catastrophic misinterpretations predicted subsequent reductions in overall symptom severity, panic attack frequency, distress/apprehension, and avoidance behavior. However, change in the various symptom domains was not typically a significant predictor of later interpretation change (except for the distress/apprehension factor). These results provide considerable support for the cognitive model of panic and speak to the temporal sequence of change processes during therapy. (c) 2010 APA, all rights reserved.

Dynamics of defensive reactivity in patients with panic disorder and agoraphobia: implications for the etiology of panic disorder.

The learning perspective of panic disorder distinguishes between acute panic and anxious apprehension as distinct emotional states. Following animal models, these clinical entities reflect different stages of defensive reactivity depending upon the imminence of interoceptive or exteroceptive threat cues. The current study tested this model by investigating the dynamics of defensive reactivity in a large group of patients with panic disorder and agoraphobia (PD/AG). Three hundred forty-five PD/AG patients participated in a standardized behavioral avoidance test (being entrapped in a small, dark chamber for 10 minutes). Defense reactivity was assessed measuring avoidance and escape behavior, self-reports of anxiety and panic symptoms, autonomic arousal (heart rate and skin conductance), and potentiation of the startle reflex before and during exposure of the behavioral avoidance test. Panic disorder and agoraphobia patients differed substantially in their defensive reactivity. While 31.6% of the patients showed strong anxious apprehension during this task (as indexed by increased reports of anxiety, elevated physiological arousal, and startle potentiation), 20.9% of the patients escaped from the test chamber. Active escape was initiated at the peak of the autonomic surge accompanied by an inhibition of the startle response as predicted by the animal model. These physiological responses resembled the pattern observed during the 34 reported panic attacks. We found evidence that defensive reactivity in PD/AG patients is dynamically organized ranging from anxious apprehension to panic with increasing proximity of interoceptive threat. These data support the learning perspective of panic disorder. Copyright © 2012 Society of Biological Psychiatry. Published by Elsevier Inc. All rights reserved.

Management of traumatic patellar dislocation in a regional hospital in Hong Kong.

Lee, H L; Yau, W P

2017-04-01

The role of surgery for acute patellar dislocation without osteochondral fracture is controversial. The aim of this study was to report the short-term results of management of patellar dislocation in our institute. Patients who were seen in our institution with patella dislocation from January 2011 to April 2014 were managed according to a standardised management algorithm. Pretreatment and 1-year post-treatment International Knee Documentation Committee score, Tegner activity level scale score, and presence of apprehension sign were analysed. A total of 41 patients were studied of whom 20 were first-time dislocators and 21 were recurrent dislocators. Among the first-time dislocators, there was a significant difference between patients who received conservative treatment versus surgical management. The conservative treatment group had a 33% recurrent dislocation rate, whereas there were no recurrent dislocations in the surgery group. There was no difference in Tegner activity level scale score or apprehension sign before and 1 year after treatment, however. Among the recurrent dislocators, there was a significant difference between those who received conservative treatment and those who underwent surgery. The recurrent dislocation rate was 71% in the conservative treatment group versus 0% in the surgery group. There was also significant improvement in International Knee Documentation Committee score from 67.7 to 80.0 (P=0.02), and of apprehension sign from 62% to 0% (P<0.01). A management algorithm for patellar dislocation is described. Surgery is preferable to conservative treatment in patients who have recurrent patellar dislocation, and may also be preferable for those who have an acute dislocation.

Homeostatic Regulation of the PI(4,5)P2-Ca2+ Signaling System at ER-PM Junctions

PubMed Central

Chang, Chi-Lun; Liou, Jen

2016-01-01

The phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2)-Ca2+ signaling system is important for cell activation in response to various extracellular stimuli. This signaling system is initiated by receptor-induced hydrolysis of PI(4,5)P2 in the plasma membrane (PM) to generate the soluble second messenger inositol 1,4,5-trisphosphate (IP3). IP3 subsequently triggers the release of Ca2+ from the endoplasmic reticulum (ER) store to the cytosol to activate Ca2+-mediated responses, such as secretion and proliferation. The consumed PM PI(4,5)P2 and ER Ca2+ must be quickly restored to sustain signaling responses, and to maintain the homeostasis of PI(4,5)P2 and Ca2+. Since phosphatidylinositol (PI), the precursor lipid for PM PI(4,5)P2, is synthesized in the ER membrane, and a Ca2+ influx across the PM is required to refill the ER Ca2+ store, efficient communications between the ER and the PM are critical for the homeostatic regulation of the PI(4,5)P2-Ca2+ signaling system. This review describes the major findings that established the framework of the PI(4,5)P2-Ca2+ signaling system, and recent discoveries on feedback control mechanisms at ER-PM junctions that sustain the PI(4,5)P2-Ca2+ signaling system. Particular emphasis is placed on the characterization of ER-PM junctions where efficient communications between the ER and the PM occurs, and the activation mechanisms of proteins that dynamically localize to ER-PM junctions to provide the feedback control during PI(4,5)P2-Ca2+ signaling, including the ER Ca2+ sensor STIM1, the extended synaptotagmin E-Syt1, and the PI transfer protein Nir2. This review is part of a Special Issue entitled The Cellular Lipid Landscape. PMID:26924250

SUMMARY Activity-dependent CREB phosphorylation and gene expression are critical for long-term neuronal plasticity. Local signaling at CaV1 channels triggers these events but how information is relayed onward to the nucleus remains unclear. Here we report a novel mechanism that mediates long-distance communication within cells: a shuttle that transports Ca2+/calmodulin from the surface membrane to the nucleus. We show that the shuttle protein is γCaMKII, that its phosphorylation at Thr287 by βCaMKII protects the Ca2+/CaM signal, and that CaN triggers its nuclear translocation. Both βCaMKII and CaN act in close proximity to CaV1 channels, supporting their dominance, while γCaMKII operates as a carrier, not as a kinase. Upon arrival within the nucleus, Ca2+/CaM activates CaMKK and its substrate CaMKIV, the CREB kinase. This mechanism resolves longstanding puzzles about CaM/CaMK-dependent signaling to the nucleus. The significance of the mechanism is emphasized by dysregulation of CaV1, γCaMKII, βCaMKII and CaN in multiple neuropsychiatric disorders. PMID:25303525

Impact of a postgraduate six-month rotation in palliative care on knowledge and attitudes of junior residents.

PubMed

Duong, Phuc H; Zulian, Gilbert B

2006-07-01

Fifty junior residents completed a six-month training period. An anonymous postal questionnaire was sent to collect the residents' opinions on improvements in their knowledge, perception of priorities and usefulness of training. Responses were rated from 5 (a great deal) to 1 (not at all improved). A total of 33 (66%) questionnaires were returned. A mean score of 4.48 was obtained on general improvement of knowledge, 4.91 +/- 0.29 on pain control, 4.17 +/- 0.58 on neurological symptoms, 4.09 +/- 0.77 on psychological symptoms, 4.64 +/- 0.60 on communication skills and 4.4 +/- 0.91 on physician attitudes. Some 58% of residents began the training with apprehension, 85% outlined their priorities and 76% reached these objectives. A total of 70% were fully satisfied with the tuition and support received and 98% recommended such clinical rotation. Data suggest that a six-month rotation in palliative care results in high levels of perception of improvement in knowledge and satisfaction. Exposure to palliative care patients during clinical rotations in specialized centres must be encouraged.

Real enough: using virtual public speaking environments to evoke feelings and behaviors targeted in stuttering assessment and treatment.

Brundage, Shelley B; Hancock, Adrienne B

Virtual reality environments (VREs) are computer-generated, 3-dimensional worlds that allow users to experience situations similar to those encountered in the real world. The purpose of this study was to investigate VREs for potential use in assessing and treating persons who stutter (PWS) by determining the extent to which PWS's affective, behavioral, and cognitive measures in a VRE correlate with those same measures in a similar live environment. Ten PWS delivered speeches-first to a live audience and, on another day, to 2 virtual audiences (neutral and challenging audiences). Participants completed standard tests of communication apprehension and confidence prior to each condition, and frequency of stuttering was measured during each speech. Correlational analyses revealed significant, positive correlations between virtual and live conditions for affective and cognitive measures as well as for frequency of stuttering. These findings suggest that virtual public speaking environments engender affective, behavioral, and cognitive reactions in PWS that correspond to those experienced in the real world. Therefore, the authentic, safe, and controlled environments provided by VREs may be useful for stuttering assessment and treatment.

It Takes Two to Talk--The Hanen Program and families of children with motor disorders: a UK perspective.

PubMed

Pennington, L; Thomson, K

2007-11-01

Speech and language therapy for young children who have motor disorders targets both the children themselves and their parents. Therapy for parents often involves training about communication and how to foster children's development. It Takes Two to Talk--The Hanen Program for Parents has become popular in the UK, but has not been specifically evaluated for this client group. This study, which was part of a larger investigation of the acceptability and potential effects of the programme on the communication patterns of mothers and their young children with motor disorders, investigated therapists' experiences of providing the training in the National Health Service (NHS) and their views on its effectiveness. Four focus groups, which involved 16 speech and language therapists who provide It Takes Two to Talk in NHS Trusts in England, were analysed using qualitative methods. The themes indicated that therapists perceived the training programme to be effective in helping parents to develop a facilitative communication style. Therapists reported secondary outcomes of positive changes in parents' confidence and in relationships between parents and their children and between parents and therapists. Barriers to the provision and success of the programme were thought to relate to resources, parents' apprehensions about the programme's content and delivery and support from key stakeholders. Barriers were seen to be minimized in services where other members of the healthcare teams actively supported the training programme and where the intervention was integrated as part of a care pathway. The information from this study may assist service providers in the marketing, planning and delivery of new intervention methods, to ensure that they are seen as valuable and acceptable by parents.

Serum deprivation induces glucose response and intercellular coupling in human pancreatic adenocarcinoma PANC-1 cells.

PubMed

2012-03-01

This study aimed to investigate whether the previously described differentiating islet-like aggregates of human pancreatic adenocarcinoma cells (PANC-1) develop glucose response and exhibit intercellular communication. Fura 2-loaded PANC-1 cells in serum-free medium were assayed for changes in cytosolic free calcium ([Ca]i) induced by depolarization, tolbutamide inhibition of K(ATP) channels, or glucose. Dye transfer, assayed by confocal microscopy or by FACS, was used to detect intercellular communication. Changes in messenger RNA (mRNA) expression of genes of interest were assessed by quantitative real-time polymerase chain reaction. Proliferation was assayed by the MTT method. Serum-deprived PANC-1 cell aggregates developed [Ca]i response to KCl, tolbutamide, or glucose. These responses were accompanied by 5-fold increase in glucokinase mRNA level and, to a lesser extent, of mRNAs for K(ATP) and L-type calcium channels, as well as increase in mRNA levels of glucagon and somatostatin. Trypsin, a proteinase-activated receptor 2 agonist previously shown to enhance aggregation, modestly improved [Ca]i response to glucose. Glucose-induced coordinated [Ca]i oscillations and dye transfer demonstrated the emergence of intercellular communication. These findings suggest that PANC-1 cells, a pancreatic adenocarcinoma cell line, can be induced to express a differentiated phenotype in which cells exhibit response to glucose and form a functional syncytium similar to those observed in pancreatic islets.

Although the role of extracellular Ca2+ draws increasing attention as a messenger in intercellular communications, there is currently no tool available for imaging Ca2+ dynamics in extracellular regions. Here we report the first solid-state fluorescent Ca2+ sensor that fulfills the essential requirements for realizing extracellular Ca2+ imaging. Inspired by natural extracellular Ca2+-sensing receptors, we designed a particular type of chemically-crosslinked polyacrylic acid gel, which can undergo single-chain aggregation in the presence of Ca2+. By attaching aggregation-induced emission luminogen to the polyacrylic acid as a pendant, the conformational state of the main chain at a given Ca2+ concentration is successfully translated into fluorescence property. The Ca2+ sensor has a millimolar-order apparent dissociation constant compatible with extracellular Ca2+ concentrations, and exhibits sufficient dynamic range and excellent selectivity in the presence of physiological concentrations of biologically relevant ions, thus enabling monitoring of submillimolar fluctuations of Ca2+ in flowing analytes containing millimolar Ca2+ concentrations.

Rem uncouples excitation–contraction coupling in adult skeletal muscle fibers

PubMed Central

Beqollari, Donald; Romberg, Christin F.; Filipova, Dilyana; Meza, Ulises; Papadopoulos, Symeon

2015-01-01

In skeletal muscle, excitation–contraction (EC) coupling requires depolarization-induced conformational rearrangements in L-type Ca2+ channel (CaV1.1) to be communicated to the type 1 ryanodine-sensitive Ca2+ release channel (RYR1) of the sarcoplasmic reticulum (SR) via transient protein–protein interactions. Although the molecular mechanism that underlies conformational coupling between CaV1.1 and RYR1 has been investigated intensely for more than 25 years, the question of whether such signaling occurs via a direct interaction between the principal, voltage-sensing α1S subunit of CaV1.1 and RYR1 or through an intermediary protein persists. A substantial body of evidence supports the idea that the auxiliary β1a subunit of CaV1.1 is a conduit for this intermolecular communication. However, a direct role for β1a has been difficult to test because β1a serves two other functions that are prerequisite for conformational coupling between CaV1.1 and RYR1. Specifically, β1a promotes efficient membrane expression of CaV1.1 and facilitates the tetradic ultrastructural arrangement of CaV1.1 channels within plasma membrane–SR junctions. In this paper, we demonstrate that overexpression of the RGK protein Rem, an established β subunit–interacting protein, in adult mouse flexor digitorum brevis fibers markedly reduces voltage-induced myoplasmic Ca2+ transients without greatly affecting CaV1.1 targeting, intramembrane gating charge movement, or releasable SR Ca2+ store content. In contrast, a β1a-binding–deficient Rem triple mutant (R200A/L227A/H229A) has little effect on myoplasmic Ca2+ release in response to membrane depolarization. Thus, Rem effectively uncouples the voltage sensors of CaV1.1 from RYR1-mediated SR Ca2+ release via its ability to interact with β1a. Our findings reveal Rem-expressing adult muscle as an experimental system that may prove useful in the definition of the precise role of the β1a subunit in skeletal-type EC coupling. PMID:26078055

Measurements of local Ca2+ signalling at different developmental stages and/or in specific cell types is important for understanding aspects of brain functioning. The use of light excitation in fluorescence imaging can cause phototoxicity, photobleaching and auto-fluorescence. In contrast, bioluminescence does not require the input of radiative energy and can therefore be measured over long periods, with very high temporal resolution. Aequorin is a genetically encoded Ca(2+)-sensitive bioluminescent protein, however, its low quantum yield prevents dynamic measurements of Ca2+ responses in single cells. To overcome this limitation, we recently reported the bi-functional Ca2+ reporter gene, GFP-aequorin (GA), which was developed specifically to improve the light output and stability of aequorin chimeras [V. Baubet, et al., (2000) PNAS, 97, 7260-7265]. In the current study, we have genetically targeted GA to different microdomains important in synaptic transmission, including to the mitochondrial matrix, endoplasmic reticulum, synaptic vesicles and to the postsynaptic density. We demonstrate that these reporters enable 'real-time' measurements of subcellular Ca2+ changes in single mammalian neurons using bioluminescence. The high signal-to-noise ratio of these reporters is also important in that it affords the visualization of Ca2+ dynamics in cell-cell communication in neuronal cultures and tissue slices. Further, we demonstrate the utility of this approach in ex-vivo preparations of mammalian retina, a paradigm in which external light input should be controlled. This represents a novel molecular imaging approach for non-invasive monitoring of local Ca2+ dynamics and cellular communication in tissue or whole animal studies.

This study was undertaken to obtain direct evidence for the involvement of gap junctions in the propagation of intercellular Ca2+ waves. Gap junction-deficient HeLa cells were transfected with plasmids encoding for green fluorescent protein (GFP) fused to the cytoplasmic carboxyl termini of connexin 43 (Cx43), 32 (Cx32), or 26 (Cx26). The subsequently expressed GFP-labeled gap junctions rendered the cells dye- and electrically coupled and were detected at the plasma membranes at points of contact between adjacent cells. To correlate the distribution of gap junctions with the changes in [Ca2+]i associated with Ca2+ waves and the distribution of the endoplasmic reticulum (ER), cells were loaded with fluorescent Ca2+-sensitive (fluo-3 and fura-2) and ER membrane (ER-Tracker) dyes. Digital high-speed microscopy was used to collect a series of image slices from which the three-dimensional distribution of the gap junctions and ER were reconstructed. Subsequently, intercellular Ca2+ waves were induced in these cells by mechanical stimulation with or without extracellular apyrase, an ATP-degrading enzyme. In untransfected HeLa cells and in the absence of apyrase, cell-to-cell propagating [Ca2+]i changes were characterized by initiating Ca2+ puffs associated with the perinuclear ER. By contrast, in Cx–GFP-transfected cells and in the presence of apyrase, [Ca2+]i changes were propagated without initiating perinuclear Ca2+ puffs and were communicated between cells at the sites of the Cx–GFP gap junctions. The efficiency of Cx expression determined the extent of Ca2+ wave propagation. These results demonstrate that intercellular Ca2+ waves may be propagated simultaneously via an extracellular pathway and an intracellular pathway through gap junctions and that one form of communication may mask the other.

Ionizing and nonionizing radiation affect not only directly targeted cells but also surrounding "bystander" cells. The underlying mechanisms and therapeutic role of bystander responses remain incompletely defined. Here we show that photosentizer activation in a single cell triggers apoptosis in bystander cancer cells, which are electrically coupled by gap junction channels and support the propagation of a Ca2+ wave initiated in the irradiated cell. The latter also acts as source of nitric oxide (NO) that diffuses to bystander cells, in which NO levels are further increased by a mechanism compatible with Ca(2+)-dependent enzymatic production. We detected similar signals in tumors grown in dorsal skinfold chambers applied to live mice. Pharmacological blockade of connexin channels significantly reduced the extent of apoptosis in bystander cells, consistent with a critical role played by intercellular communication, Ca2+ and NO in the bystander effects triggered by photodynamic therapy.

Teaching vs. Preaching: Complex Climate Shown Simply

Unger, M.; Besser, N.

Stepping outside of traditional educational venues to reach people in ways they can relate to is critical in engaging the public in topics that are complex and subtle, particularly those that have become polarized and misunderstood. The National Center for Atmospheric Research (NCAR) recently designed a visitor center for its new supercomputing facility that incorporates a variety of elements intended to draw visitors in, pique their curiosity, and invite them to explore the world of climate science from a fresh perspective. We made use of video storytelling, highlighting the people at the heart of the research, to present information in a conversational tone while captivating visitors with stunning images and music. We also designed interactive games to illustrate concepts like parallel processing, and how those, in turn, apply to understanding climate. And in addition to more traditional kinesthetic displays, we are exploring ways to use social media as a means of interacting with our audiences. One of the newer modes of communication we've adopted has been cartoon storytelling. Two dimensional cartoon animation has strong cultural connotations of levity and fun. For this reason it has proven to be a particularly useful tool in communicating climate science as it disarms the viewer from the apprehension of trying to understand a great deal of scientific jargon. By crafting key concepts into scripts and using appropriate metaphors with a dash of humor we have been able to reach a far broader audience without sacrificing the science or the message.

However, the tissue is extensively innervated and communication between epithelium and neurons is critical and not well understood. Therefore, we developed a co-culture of primary trigeminal neurons and human corneal limbal epithelial cells. We demonstrated that trigeminal neurons expressed a repertoire of P2Yand P2X receptor transcripts and responded to P2 agonists in a concentration-dependent manner. Mechanical injuries to epithelia in the co-cultures elicited a Ca(2+) wave that mobilized to neurons and was attenuated by Apyrase, an ectonucleotidase. To elucidate the role of factors released from each cell type, epithelial and neuronal cells were cultured, injured, and the wound media from one cell type was collected and added to the other cell type. Epithelial wound media generated a rapid Ca(2+) mobilization in neuronal cells that was abrogated in the presence of Apyrase, while neuronal wound media elicited a complex response in epithelial cells. The rapid Ca(2+) mobilization was detected, which was abrogated with Apyrase, but it was followed by Ca(2+) waves that occurred in cell clusters. When neuronal wound media was preincubated with a cocktail of N-methyl-D-aspartate (NMDA) receptor inhibitors, the secondary response in epithelia was diminished. Glutamate was detected in the neuronal wound media and epithelial expression of NMDA receptor subunit transcripts was demonstrated. Our results indicate that corneal epithelia and neurons communicate via purinergic and NMDA receptors that mediate the wound response in a highly orchestrated manner.

Solo status and self-construal: being distinctive influences racial self-construal and performance apprehension in African American women.

PubMed

2007-10-01

A preliminary study and main experiment tested the hypothesis that racial solo status (being the only member of one's race in a group) increases racial self-construal among African Americans. The preliminary study showed that African American men and women reported greater collectivist (i.e., group-based) over individualist self-construal under solo compared to nonsolo status, whereas Whites did not. The main experiment showed that the increased collectivism among African American solo women appears to be strongly reflected in racial identity becoming a salient aspect of self-construal. African American participants were also more likely than Whites to perceive that their anticipated performance would be generalized to their race, to feel like representatives of their race, and to show greater performance apprehension (indirectly evidenced by increased self-handicapping) when in racial solo status. The implications of solo status for African Americans in evaluative situations (such as academic testing sessions) are discussed. 2007 APA

Background Habituation of the fear response, critical for the treatment of anxiety, is inconsistently observed during exposure to threatening stimuli. One potential explanation for this inconsistency is differential attentional engagement with negatively valenced stimuli as a function of anxiety type. Methods The present study tested this hypothesis by examining patterns of neural habituation associated with anxious arousal, characterized by panic symptoms and immediate engagement with negatively valenced stimuli, versus anxious apprehension, characterized by engagement in worry to distract from negatively valenced stimuli. Results As predicted, the two anxiety types evidenced distinct patterns of attentional engagement. Anxious arousal was associated with immediate activation in attention-related brain regions that habituated over time, whereas anxious apprehension was associated with delayed activation in attention-related brain regions that occurred only after habituation in a worry-related brain region. Conclusions Results further elucidate mechanisms involved in attention to negatively valenced stimuli and indicate that anxiety is a heterogeneous construct with regard to attention to such stimuli.

When the threat comes from inside the body: a neuroscience based learning perspective of the etiology of panic disorder.

PubMed

Hamm, Alfons O; Richter, Jan; Pané-Farré, Christiane A

2014-01-01

Unexpected, recurrent panic attacks and anxious apprehension are two distinct emotional phenomena that constitute the core symptoms for diagnosing panic disorder. Taking a neuroscience perspective the current review paper presents both epidemiological and experimental psychophysiological evidence suggesting that panic attacks can be conceptualized as an unconditioned circa defense response pattern to intense internal threat stimuli, characterized by strong autonomic surge and escape behavior and abnormal plastic changes of the brain. Anxious apprehension develops after the experience of such severe panic attacks as conditioned responses to mild body symptoms. Theoretically these conditioned fear responses can be considered as post-encounter defense characterized by increased selective attention, increased threat appraisal and defensive freezing and startle potentiation evidencing altered brain circuits evoked by mild body symptoms. Agoraphobic avoidance starts very early during the defensive cascade and can be conceived as motivated behavior driven by the incentive to be in a safe context that is under control of the individual.

Crime and punishment: Does it pay to punish?

NASA Astrophysics Data System (ADS)

Iglesias, J. R.; Semeshenko, V.; Schneider, E. M.; Gordon, M. B.

2012-08-01

Crime is the result of a rational distinctive balance between the benefits and costs of an illegal act. This idea was proposed by Becker more than forty years ago (Becker (1968) [1]). In this paper, we simulate a simple artificial society, in which agents earn fixed wages and can augment (or lose) wealth as a result of a successful (or not) act of crime. The probability of apprehension depends on the gravity of the crime, and the punishment takes the form of imprisonment and fines. We study the costs of the law enforcement system required for keeping crime within acceptable limits, and compare it with the harm produced by crime. A sharp phase transition is observed as a function of the probability of punishment, and this transition exhibits a clear hysteresis effect, suggesting that the cost of reversing a deteriorated situation might be much higher than that of maintaining a relatively low level of delinquency. Besides, we analyze economic consequences that arise from crimes under different scenarios of criminal activity and probabilities of apprehension.

2012-01-01

Objective This study aimed to investigate whether the previously described differentiating islet-like aggregates of human pancreatic adenocarcinoma cells (PANC-1) develop glucose response and exhibit intercellular communication. Methods Fura 2–loaded PANC-1 cells in serum-free medium were assayed for changes in cytosolic free calcium ([Ca]i) induced by depolarization, tolbutamide inhibition of K(ATP) channels, or glucose. Dye transfer, assayed by confocal microscopy or by FACS, was used to detect intercellular communication. Changes in messenger RNA (mRNA) expression of genes of interest were assessed by quantitative real-time polymerase chain reaction. Proliferation was assayed by the MTT method. Results Serum-deprived PANC-1 cell aggregates developed [Ca]i response to KCl, tolbutamide, or glucose. These responses were accompanied by 5-fold increase in glucokinase mRNA level and, to a lesser extent, of mRNAs for K(ATP) and L-type calcium channels, as well as increase in mRNA levels of glucagon and somatostatin. Trypsin, a proteinase-activated receptor 2 agonist previously shown to enhance aggregation, modestly improved [Ca]i response to glucose. Glucose-induced coordinated [Ca]i oscillations and dye transfer demonstrated the emergence of intercellular communication. Conclusions These findings suggest that PANC-1 cells, a pancreatic adenocarcinoma cell line, can be induced to express a differentiated phenotype, in which cells exhibit response to glucose and form a functional syncytium similar to those observed in pancreatic islets.

Prostate cancer survivors as community health educators: implications for informed decision making and cancer communication.

2013-12-01

Recent evidence questioning the effectiveness of prostate-specific antigen testing leave community-based prostate cancer (CaP) outreach programs with a dilemma between promoting screening and highlighting screening risks. CaP survivors are uniquely positioned to address this problem by drawing upon real-life experiences to share nuanced information and perspectives. While CaP survivors have historically been incorporated into outreach programs, little is known about their impact on psychosocial outcomes and their effectiveness compared to professional health educators. This study addressed these gaps through a quasi-experimental design where African American men attended a CaP screening session conducted by a health educator (HE) or survivor educator (SV). The presentation included prostate cancer statistics, CaP information, and descriptions of CaP screening tests. SV were encouraged to bolster their presentations with personal stories whereas HE maintained fidelity to the curriculum content. All participants completed pre- and post-test questionnaires. Our sample comprised a total of 63 participants (HE group = 32; SV group = 31) with an age range of 40-70 years. Decision self-efficacy increased significantly in the SV group (p = 0.01) whereas perceived screening risks reduced significantly in the HE group (p < 0.001). No significant changes were found in knowledge, subjective norms, outcome expectancies, and screening benefits. Survivor educators were found to have significantly greater appeal (p = 0.03), identification with audience (p = 0.01), and liking (p = 0.03). Training CaP survivors as health educators might be a viable strategy for community-based cancer communication efforts confronted by the CaP screening controversy. We discuss conceptual and programmatic implications of our findings and present directions for future research.

A tidal wave of signals: calcium and ROS at the forefront of rapid systemic signaling.

PubMed

Gilroy, Simon; Suzuki, Nobuhiro; Miller, Gad; Choi, Won-Gyu; Toyota, Masatsugu; Devireddy, Amith R; Mittler, Ron

2014-10-01

Systemic signaling pathways enable multicellular organisms to prepare all of their tissues and cells to an upcoming challenge that may initially only be sensed by a few local cells. They are activated in plants in response to different stimuli including mechanical injury, pathogen infection, and abiotic stresses. Key to the mobilization of systemic signals in higher plants are cell-to-cell communication events that have thus far been mostly unstudied. The recent identification of systemically propagating calcium (Ca(2+)) and reactive oxygen species (ROS) waves in plants has unraveled a new and exciting cell-to-cell communication pathway that, together with electric signals, could provide a working model demonstrating how plant cells transmit long-distance signals via cell-to-cell communication mechanisms. Here, we summarize recent findings on the ROS and Ca(2+) waves and outline a possible model for their integration. Copyright © 2014 Elsevier Ltd. All rights reserved.

Mission operations and command assurance: Instilling quality into flight operations

NASA Technical Reports Server (NTRS)

Welz, Linda L.; Witkowski, Mona M.; Bruno, Kristin J.; Potts, Sherrill S.

1993-01-01

Mission Operations and Command Assurance (MO&CA) is a Total Quality Management (TQM) task on JPL projects to instill quality in flight mission operations. From a system engineering view, MO&CA facilitates communication and problem-solving among flight teams and provides continuous process improvement to reduce the probability of radiating incorrect commands to a spacecraft. The MO&CA task has evolved from participating as a member of the spacecraft team to an independent team reporting directly to flight project management and providing system level assurance. JPL flight projects have benefited significantly from MO&CA's effort to contain risk and prevent rather than rework errors. MO&CA's ability to provide direct transfer of knowledge allows new projects to benefit from previous and ongoing flight experience.

Calmodulin shuttling mediates cytonuclear signaling to trigger experience-dependent transcription and memory.

Learning and memory depend on neuronal plasticity originating at the synapse and requiring nuclear gene expression to persist. However, how synapse-to-nucleus communication supports long-term plasticity and behavior has remained elusive. Among cytonuclear signaling proteins, γCaMKII stands out in its ability to rapidly shuttle Ca 2+ /CaM to the nucleus and thus activate CREB-dependent transcription. Here we show that elimination of γCaMKII prevents activity-dependent expression of key genes (BDNF, c-Fos, Arc), inhibits persistent synaptic strengthening, and impairs spatial memory in vivo. Deletion of γCaMKII in adult excitatory neurons exerts similar effects. A point mutation in γCaMKII, previously uncovered in a case of intellectual disability, selectively disrupts CaM sequestration and CaM shuttling. Remarkably, this mutation is sufficient to disrupt gene expression and spatial learning in vivo. Thus, this specific form of cytonuclear signaling plays a key role in learning and memory and contributes to neuropsychiatric disease.

Calcium sequestration by fungal melanin inhibits calcium-calmodulin signalling to prevent LC3-associated phagocytosis.

LC3-associated phagocytosis (LAP) is a non-canonical autophagy pathway regulated by Rubicon, with an emerging role in immune homeostasis and antifungal host defence. Aspergillus cell wall melanin protects conidia (spores) from killing by phagocytes and promotes pathogenicity through blocking nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-dependent activation of LAP. However, the signalling regulating LAP upstream of Rubicon and the mechanism of melanin-induced inhibition of this pathway remain incompletely understood. Herein, we identify a Ca 2+ signalling pathway that depends on intracellular Ca 2+ sources from endoplasmic reticulum, endoplasmic reticulum-phagosome communication, Ca 2+ release from phagosome lumen and calmodulin (CaM) recruitment, as a master regulator of Rubicon, the phagocyte NADPH oxidase NOX2 and other molecular components of LAP. Furthermore, we provide genetic evidence for the physiological importance of Ca 2+ -CaM signalling in aspergillosis. Finally, we demonstrate that Ca 2+ sequestration by Aspergillus melanin inside the phagosome abrogates activation of Ca 2+ -CaM signalling to inhibit LAP. These findings reveal the important role of Ca 2+ -CaM signalling in antifungal immunity and identify an immunological function of Ca 2+ binding by melanin pigments with broad physiological implications beyond fungal disease pathogenesis.

Critical role of gap junction communication, calcium and nitric oxide signaling in bystander responses to focal photodynamic injury

Ionizing and nonionizing radiation affect not only directly targeted cells but also surrounding “bystander” cells. The underlying mechanisms and therapeutic role of bystander responses remain incompletely defined. Here we show that photosentizer activation in a single cell triggers apoptosis in bystander cancer cells, which are electrically coupled by gap junction channels and support the propagation of a Ca2+ wave initiated in the irradiated cell. The latter also acts as source of nitric oxide (NO) that diffuses to bystander cells, in which NO levels are further increased by a mechanism compatible with Ca2+-dependent enzymatic production. We detected similar signals in tumors grown in dorsal skinfold chambers applied to live mice. Pharmacological blockade of connexin channels significantly reduced the extent of apoptosis in bystander cells, consistent with a critical role played by intercellular communication, Ca2+ and NO in the bystander effects triggered by photodynamic therapy.

2016-10-01

A sunken soft-spot or fontanel is a sign for dehydration in infants. Around the world, folk illnesses, such as caída de la mollera in some Latin American cultures, often incorporate this sign as a hallmark of illness, but may or may not incorporate re-hydration therapies in treatment strategies. This report describes a study of lay descriptions of causes, symptoms, and treatments for caída de la mollera in three diverse Latin American populations. A mixed-methods approach was used. Representative community-based samples were interviewed in rural Guatemala, Guadalajara, Mexico, and Edinburgh, Texas, with a 132 item questionnaire on the causes, susceptibility, symptoms, and therapies for caída de la mollera. Cultural consensus analysis was used to estimate community beliefs about caída. Interviews conducted in rural Guatemala (n = 60), urban Mexico (n = 62), and rural Texas on the Mexican border (n = 61) indicated consistency in thematic elements within and among these three diverse communities. The high degree of consistency in the illness explanatory models indicated shared beliefs about caída de la mollera in each of the communities and a core model shared across communities. However, an important aspect of the community beliefs was that rehydration therapies were not widely endorsed. The consistency in explanatory models in such diverse communities, as well as the high degree of recognition and experience with this illness, may facilitate communication between community members, and health care providers/public health intervention planners to increase use of rehydration therapies for caída de la mollera. Recommendations for culturally informed and respectful approaches to clinical communication are provided.

Student anxiety in introductory biology classrooms: Perceptions about active learning and persistence in the major.

PubMed

England, Benjamin J; Brigati, Jennifer R; Schussler, Elisabeth E

2017-01-01

Many researchers have called for implementation of active learning practices in undergraduate science classrooms as one method to increase retention and persistence in STEM, yet there has been little research on the potential increases in student anxiety that may accompany these practices. This is of concern because excessive anxiety can decrease student performance. Levels and sources of student anxiety in three introductory biology lecture classes were investigated via an online survey and student interviews. The survey (n = 327) data revealed that 16% of students had moderately high classroom anxiety, which differed among the three classes. All five active learning classroom practices that were investigated caused student anxiety, with students voluntarily answering a question or being called on to answer a question causing higher anxiety than working in groups, completing worksheets, or answering clicker questions. Interviews revealed that student anxiety seemed to align with communication apprehension, social anxiety, and test anxiety. Additionally, students with higher general anxiety were more likely to self-report lower course grade and the intention to leave the major. These data suggest that a subset of students in introductory biology experience anxiety in response to active learning, and its potential impacts should be investigated.

2015-01-01

Access to social services is important for the safety of children and ultimately for reunification of families involved in the child welfare system. The process of linking families to services however, varies by caseworker and can be cumbersome and time-consuming. The DCFS Needs Portal is an internet-based intervention to improve the timing and quality of social service referrals in Los Angeles County We used a case study approach including in-depth interviews, direct observations and user feedback obtained from the Needs Portal to 1) determine perceived benefits and barriers to adopting the Needs Portal and 2) report how the flow of information between users and developers was used to adapt to user needs. Our analyses revealed four major barriers: 1) caseworker apprehension regarding new technology, 2) variation in communication styles by user type, 3) lack of technological infrastructure and 4) competing workplace demands. Information sharing between developers and users has the potential to better meet the needs of users and ultimately maximize utilization of new technology. Although internet-based interventions are designed to inexpensively and effectively coordinate services, emerging interventions may require in-person assistance and modifications in order to succeed.

Mission Operations and Command Assurance (MO&CA) is a Total Quality Management (TQM) task on JPL projects to instill quality in flight mission operations. From a system engineering view, MO&CA facilitates communication and problem-solving among flight teams and provides continuous solving among flight teams and provides continuous process improvement to reduce risk in mission operations by addressing human factors. The MO&CA task has evolved from participating as a member of the spacecraft team, to an independent team reporting directly to flight project management and providing system level assurance. JPL flight projects have benefited significantly from MO&CA's effort to contain risk and prevent rather than rework errors. MO&CA's ability to provide direct transfer of knowledge allows new projects to benefit from previous and ongoing flight experience.

Allosteric mechanism of water channel gating by Ca2+–calmodulin

Reichow, Steve L.; Clemens, Daniel M.; Freites, J. Alfredo; Németh-Cahalan, Karin L.; Heyden, Matthias; Tobias, Douglas J.; Hall, James E.; Gonen, Tamir

Calmodulin (CaM) is a universal regulatory protein that communicates the presence of calcium to its molecular targets and correspondingly modulates their function. This key signaling protein is important for controlling the activity of hundreds of membrane channels and transporters. However, our understanding of the structural mechanisms driving CaM regulation of full-length membrane proteins has remained elusive. In this study, we determined the pseudo-atomic structure of full-length mammalian aquaporin-0 (AQP0, Bos Taurus) in complex with CaM using electron microscopy to understand how this signaling protein modulates water channel function. Molecular dynamics and functional mutation studies reveal how CaM binding inhibits AQP0 water permeability by allosterically closing the cytoplasmic gate of AQP0. Our mechanistic model provides new insight, only possible in the context of the fully assembled channel, into how CaM regulates multimeric channels by facilitating cooperativity between adjacent subunits.

The Land of the Summer People, a multidisciplinary educational experiment in flooding

NASA Astrophysics Data System (ADS)

Fernández Arconada, S.; Wagener, T.

2015-12-01

Our changing climate brings with it unpredictable extreme weather events.Therefore working creatively with communities to generate sustainable solutions becomes vital, to be more resilient to an uncertain environmental future. The Land of the Summer People (TLOTSP) is an experiment regarding the unstable relationship between society, water and place by exploring flooding impacts in Somerset (UK). Using creative and scientific methods this multidisciplinary project applies participatory research to understand societal responses to extreme weather events, including academics, practitioners and local communities to generate an open dialogue from the local to the global (climate change). TLOTSP is a joint project between and artist and an engineer. During this project the artist developed a number of creative activities to facilitate dialogue with both engineering students and local artists working together in the case study: Flooding in Somerset Levels and Moors. Each working group generated a particular method to work in collaboration, together with locals in Somerset, while also creating an artistic outcome as a result of the process. We worked around communication looking at how disciplinary training [academics] acquire the capacity for the specialised "coding" of information, a language that detaches from the wider apprehension. We asked whether art could offer a language to facilitate the process of "decoding" knowledge. In addition, we looked at how communities affected by extreme weather events perceive and communicate the historical context, realising that responses are determined by living memory rather than archival history. This helped us to understand how short-term connections with nature have shaped the way we live today.

Exploring the decision to disclose the use of natural products among outpatients: a mixed-method study

PubMed Central

2013-01-01

Background There is little understanding of the reasons for the limited communication between patients and conventional healthcare professionals regarding patients’ use of complementary and alternative medicine (CAM). The purpose of this study is to explore the predictors of outpatients’ decision to disclose their use of natural products to conventional healthcare professionals. Methods A mixed method design was used. Quantitative data were obtained through a survey and qualitative data were obtained from semi-structured interviews. A total of 257 outpatients who fulfilled the criteria of having used natural products prior to the interview were recruited for this study. Subsequently, 39 patients of those who completed the survey were further selected to take part in an in-depth qualitative interview. Results Predictors of the decision to disclose the use of natural products to conventional healthcare professionals included age, frequency of clinic visits, knowledge of the natural products and the attitude towards the benefits of CAM use. The themes that emerged from the qualitative data included safeness of the natural products, consulting alternative sources of information, apprehension regarding the development of negative relationships with healthcare professionals and reactions from the healthcare professionals. Conclusions Understanding the factors and reasons affecting patients’ decision as to whether to disclose their use of natural products provides an opportunity for conventional healthcare professionals to communicate better with patients. It is important to encourage patients to disclose their use of natural products in order to provide responsible health care as well as increasing patient safety regarding medication usage.

Memory retrieval along the proximodistal axis of CA1.

PubMed

Nakazawa, Yuki; Pevzner, Aleksandr; Tanaka, Kazumasa Z; Wiltgen, Brian J

2016-09-01

The proximal and distal segments of CA1 are thought to perform distinct computations. Neurons in proximal CA1 are reciprocally connected with the medial entorhinal cortex (MEC) and exhibit precise spatial firing. In contrast, cells in distal CA1 communicate with the lateral entorhinal cortex (LEC), exhibit more diffuse spatial firing and are affected by the presence of objects in the environment. To determine if these segments make unique contributions to memory retrieval, we examined cellular activity along the proximodistal axis of CA1 using transgenic reporter mice. Neurons tagged during context learning in proximal CA1 were more likely to be reactivated during testing than those in distal CA1. This was true following context fear conditioning and after exposure to a novel environment. Reactivation was also higher in brain regions connected to proximal CA1 (MEC, distal CA3) than those connected to the distal segment (LEC, proximal CA3). To examine contributions to memory retrieval, we performed neurotoxic lesions of proximal or distal CA1 after training. Lesions of the proximal segment significantly impaired memory retrieval while damage to distal CA1 had no effect. These data suggest that context memories are retrieved by a hippocampal microcircuit that involves the proximal but not distal segment of CA1. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Cognitive processing specificity of anxious apprehension: impact on distress and performance during speech exposure.

PubMed

Philippot, Pierre; Vrielynck, Nathalie; Muller, Valérie

2010-12-01

The present study examined the impact of different modes of processing anxious apprehension on subsequent anxiety and performance in a stressful speech task. Participants were informed that they would have to give a speech on a difficult topic while being videotaped and evaluated on their performance. They were then randomly assigned to one of three conditions. In a specific processing condition, they were encouraged to explore in detail all the specific aspects (thoughts, emotions, sensations) they experienced while anticipating giving the speech; in a general processing condition, they had to focus on the generic aspects that they would typically experience during anxious anticipation; and in a control, no-processing condition, participants were distracted. Results revealed that at the end of the speech, participants in the specific processing condition reported less anxiety than those in the two other conditions. They were also evaluated by judges to have performed better than those in the control condition, who in turn did better than those in the general processing condition. Copyright © 2010.

The “Gray Zone” of Police Work During Mental Health Encounters: Findings from an Observational Study in Chicago

PubMed Central

Wood, Jennifer D; Watson, Amy C; Fulambarker, Anjali J

2016-01-01

Although improving police responses to mental health crises has received significant policy attention, most encounters between police and persons with mental illnesses do not involve major crimes or violence, nor do they rise to the level of requiring emergency apprehension. Here, we report on field observations of police officers handling mental health-related encounters in Chicago. Findings confirm that these encounters often occur in the “gray zone”, where the problems at hand do not call for formal or legalistic interventions including arrest and emergency apprehension. In examining how police resolved such situations, we observed three core features of police work: (1) accepting temporary solutions to chronic vulnerability; (2) using local knowledge to guide decision-making; and (3) negotiating peace with complainants and call subjects. Study findings imply the need to advance field-based studies using systematic social observations of gray zone decision-making within and across distinct geographic and place-based contexts. Policy implications for supporting police interventions, including place-based enhancements of gray zone resources, are also discussed. PMID:28286406

A qualitative analysis of implementing shared decision making in Child and Adolescent Mental Health Services in the United Kingdom: Stages and facilitators.

To explore the implementation of shared decision making (SDM) in Child and Adolescent Mental Health Services (CAMHS), and identify clinician-determined facilitators to SDM. Professionals from four UK CAMHS tried a range of tools to support SDM. They reflected on their experiences using plan-do-study-act log books. A total of 23 professionals completed 307 logs, which were transcribed and analysed using Framework Analysis in Atlas.Ti. Three states of implementation (apprehension, feeling clunky, and integration) and three aspects of clinician behavior or approach (effort, trust, and flexibility) were identified. Implementation of SDM in CAMHS requires key positive clinician behaviors, including preparedness to put in effort, trust in young people, and use of the approach flexibly. Implementation of SDM in CAMHS is effortful, and while tools may help support SDM, clinicians need to be allowed to use the tools flexibly to allow them to move from a state of apprehension through a sense of feeling "clunky" to integration in practice. © The Author(s) 2014.

Options to avoid the second surgical site: a review of literature.

PubMed

Ramachandra, Srinivas Sulugodu; Rana, Ritu; Reetika, Singhal; Jithendra, K D

2014-09-01

As esthetics gain importance, periodontal plastic surgical procedures involving soft tissue grafts are becoming commoner both around natural teeth as well as around implants. Periodontal soft tissue grafts are primarily used for the purpose of root coverage and in pre-prosthetic surgery to thicken a gingival site or to improve the crestal volume. Soft tissue grafts are usually harvested from the palate. Periodontal plastic surgical procedures involving soft tissue grafts harvested from the palate have two surgical sites; a recipient site and another donor site. Many patients are apprehensive about the soft tissue graft procedures, especially the creation of the second/donor surgical site in the palate. In the past decade, newer techniques and products have emerged which provide an option for the periodontist/patient to avoid the second surgical site. MucoMatrixX, Alloderm(®), Platelet rich fibrin, Puros(®) Dermis and Mucograft(®) are the various options available to the practicing periodontist to avoid the second surgical site. Use of these soft tissue allografts in an apprehensive patient would decrease patient morbidity and increase patient's acceptance towards periodontal plastic surgical procedures.

There have been no changes to the statutory penalties for cannabis use in New Zealand for over 35 years and this has attracted some criticism. However, statutory penalties often provide a poor picture of the actual criminal justice outcomes for minor drug offending. To examine criminal justice outcomes for cannabis use offences in New Zealand over the past two decades. Rates of apprehension, prosecution, conviction and related criminal justice outcomes for the use of cannabis in New Zealand (per 100,000 population) were calculated for 1991-2008. The same measures were calculated (per 1000 last year cannabis users) for 1998, 2001, 2003 and 2006. Trends were tested for using logistic regression with year predicting each measure outcome and with chi-square tests. The number of police apprehensions for cannabis use per year (per 100,000 population) declined from 468 in 1994 to 247 in 2008. The number of apprehensions for cannabis use per year (per 1000 cannabis users) also declined from 36 in 1998 to 21 in 2006. There were similar declines in prosecutions and convictions for cannabis use from 1991 to 2008. Those prosecuted for cannabis use in 2000-2008 were less likely than those prosecuted in 1991-1999 to be convicted and were more likely to be diverted away from the courts, 'discharged without conviction' and 'convicted and discharged'. There has been a substantial decline in arrests for cannabis use in New Zealand over the past decade and this lead to similar declines in prosecutions and convictions for cannabis use. The decline in convictions for cannabis use was further assisted by the expansion of police diversion to include cannabis use offences. Our findings underline the importance of examining the implementation of law, as well as statutory penalties, when characterising a country's criminal justice approach to minor drug offending.

Mutation of a NCKX Eliminates Glial Microdomain Calcium Oscillations and Enhances Seizure Susceptibility

PubMed Central

Melom, Jan E.; Littleton, J. Troy

2013-01-01

Glia exhibit spontaneous and activity-dependent fluctuations in intracellular Ca2+, yet it is unclear whether glial Ca2+ oscillations are required during neuronal signaling. Somatic glial Ca2+ waves are primarily mediated by the release of intracellular Ca2+ stores, and their relative importance in normal brain physiology has been disputed. Recently, near-membrane microdomain Ca2+ transients were identified in fine astrocytic processes and found to arise via an intracellular store-independent process. Here, we describe the identification of rapid, near-membrane Ca2+ oscillations in Drosophila cortex glia of the CNS. In a screen for temperature-sensitive conditional seizure mutants, we identified a glial-specific Na+/Ca2+, K+ exchanger (zydeco) that is required for microdomain Ca2+ oscillatory activity. We found that zydeco mutant animals exhibit increased susceptibility to seizures in response to a variety of environmental stimuli, and that zydeco is required acutely in cortex glia to regulate seizure susceptibility. We also found that glial expression of calmodulin is required for stress-induced seizures in zydeco mutants, suggesting a Ca2+/calmodulin-dependent glial signaling pathway underlies glial–neuronal communication. These studies demonstrate that microdomain glial Ca2+ oscillations require NCKX-mediated plasma membrane Ca2+ flux, and that acute dysregulation of glial Ca2+ signaling triggers seizures.

Active Generation and Propagation of Ca2+ Signals within Tunneling Membrane Nanotubes

PubMed Central

Smith, Ian F.; Shuai, Jianwei; Parker, Ian

2011-01-01

A new mechanism of cell-cell communication was recently proposed after the discovery of tunneling nanotubes (TNTs) between cells. TNTs are membrane protrusions with lengths of tens of microns and diameters of a few hundred nanometers that permit the exchange of membrane and cytoplasmic constituents between neighboring cells. TNTs have been reported to mediate intercellular Ca2+ signaling; however, our simulations indicate that passive diffusion of Ca2+ ions alone would be inadequate for efficient transmission between cells. Instead, we observed spontaneous and inositol trisphosphate (IP3)-evoked Ca2+ signals within TNTs between cultured mammalian cells, which sometimes remained localized and in other instances propagated as saltatory waves to evoke Ca2+ signals in a connected cell. Consistent with this, immunostaining showed the presence of both endoplasmic reticulum and IP3 receptors along the TNT. We propose that IP3 receptors may actively propagate intercellular Ca2+ signals along TNTs via Ca2+-induced Ca2+ release, acting as amplification sites to overcome the limitations of passive diffusion in a chemical analog of electrical transmission of action potentials.

GLP-1 promotes mitochondrial metabolism in vascular smooth muscle cells by enhancing endoplasmic reticulum-mitochondria coupling.

Incretin GLP-1 has important metabolic effects on several tissues, mainly through the regulation of glucose uptake and usage. One mechanism for increasing cell metabolism is modulating endoplasmic reticulum (ER)-mitochondria communication, as it allows for a more efficient transfer of Ca(2+) into the mitochondria, thereby increasing activity. Control of glucose metabolism is essential for proper vascular smooth muscle cell (VSMC) function. GLP-1 has been shown to produce varied metabolic actions, but whether it regulates glucose metabolism in VSMC remains unknown. In this report, we show that GLP-1 increases mitochondrial activity in the aortic cell line A7r5 by increasing ER-mitochondria coupling. GLP-1 increases intracellular glucose and diminishes glucose uptake without altering glycogen content. ATP, mitochondrial potential and oxygen consumption increase at 3h of GLP-1 treatment, paralleled by increased Ca(2+) transfer from the ER to the mitochondria. Furthermore, GLP-1 increases levels of Mitofusin-2 (Mfn2), an ER-mitochondria tethering protein, via a PKA-dependent mechanism. Accordingly, PKA inhibition and Mfn2 down-regulation prevented mitochondrial Ca(2+) increases in GLP-1 treated cells. Inhibiting both Ca(2+) release from the ER and Ca(2+) entry into mitochondria as well as diminishing Mfn2 levels blunted the increase in mitochondrial activity in response to GLP-1. Altogether, these results strongly suggest that GLP-1 increases ER-mitochondria communication in VSMC, resulting in higher mitochondrial activity. Copyright © 2014 Elsevier Inc. All rights reserved.

Aging out in the desert: disclosure, acceptance, and service use among midlife and older lesbians and gay men.

Lesbian, gay, bisexual, and transgender (LGBT) persons in the county of Riverside, CA and in the Palm Springs/Coachella Valley area, in particular, responded to a questionnaire addressing concerns about identity disclosure and comfort accessing social services. Distributed at a Pride festival, as well as through religious, social, and service agencies, the final sample for analysis of 502 comprised 401 (80%) gay men and 101 (20%) lesbians in 4 groups: < 50 years of age (18%), 50 to 59 (26%), 60 to 69 (36%), and over 70 (20%). Results reveal that almost one-third of midlife and older gay men and lesbians maintain some fear of openly disclosing their sexual orientation. Along comparable lines with similar proportions, older gay men and lesbians maintain some discomfort in their use of older adult social services, even as the majority reports that they would feel more comfortable accessing LGBT-friendly identified services and programs. In both cases, lesbians reported greater fear and discomfort than did gay men; older gay men and lesbians reported that they would be less comfortable accessing LGBT-identified services and programs than did younger gay men and lesbians. These data support prior research on the apprehension of LGBT elders in accessing care, the crucial role of acceptance, with some suggestions of how social services might better prepare to address these needs.

The effects of two EFL (English as a foreign language) teaching approaches studied by the cotwin control method: a comparative study of the communicative and the grammatical approaches.

Ando, J

1992-01-01

The present study compared two different types of English-language teaching approaches, the grammatical approach (GA) and the communicative approach (CA), by the cotwin control method. This study has two purposes: to study the effects of teaching approaches and to estimate genetic influences upon learning aptitudes. Seven pairs of identical twins (MZ) and 4 pairs of fraternal twins (DZ) participated in the experiment along with 68 other nontwin fifth graders. Each cotwin was assigned to the GA and CA respectively and received 20 hours of lessons over a 10-day period. The behavioral similarities between MZ cotwins were statistically and descriptively depicted. No major effect of either teaching approach was noted, but the genetic influence upon individual differences of learning achievement was obvious. Furthermore, an interesting interaction between the teaching approaches and intelligence was found, that is, that the GA capitalises on and CA compensates for intelligence. This interactional pattern could be interpreted as an example of genotype-environment interaction. The relationship between genetic factors and learning aptitudes is discussed.

Nanometer-spaced appositions between endoplasmic reticulum and plasma membrane (ER-PM junctions) stabilized by membrane-joining protein complexes are critically involved in cellular Ca 2+ -handling and lipid trafficking. ER-PM junctional architecture and plasticity associated with inter-membrane communication are as yet barely understood. Here, we introduce a method to precisely characterize ER-PM junction morphology and dynamics with high temporal resolution and minimal disturbance of junctional intermembrane communication. We show that expression of soluble cytosolic fluorophores in combination with TIRFM enables to delineate ER and PM distance in the range of 10-150 nm. Live-cell imaging of sub-plasmalemmal structures in RBL-2H3 mast cells by this method, designated as fluorescence density mapping (FDM), revealed profound dynamics of ER-PM contact sites in response to store-depletion. We report the existence of a Ca 2+ -dependent process that expands the junctional ER to enlarge its contact surface with the PM, thereby promoting and stabilizing STIM1-Orai1 competent ER-PM junctions.

African American men's understanding and perceptions about prostate cancer: why multiple dimensions of health literacy are important in cancer communication.

Friedman, Daniela B; Corwin, Sara J; Dominick, Gregory M; Rose, India D

2009-10-01

Prostate cancer (PrCA) is the most diagnosed cancer among men in the United States, especially among African American (AA) men. The purpose of this formative study was to explore the implications of applying Nutbeam's multidimensional health literacy framework to AA men's understanding of PrCA information. Participants were 25 AA men aged 45 and older in South Carolina. Their functional health literacy was assessed using two modified Cloze tests and the Shortened Test of Functional Health Literacy in Adults (S-TOFHLA). Men also participated in interviews or focus groups during which they were asked questions about PrCA risk, prevention, and screening. Transcripts were reviewed for recurrent themes and analyzed qualitatively using NVivo7. Mean S-TOFHLA was 28.28 (+/-1.98), implying "adequate" comprehension. Mean Cloze was .71 (+/-.05) for a Grade 8 document and .66 (+/-.04) for a Grade 13 document, also showing "adequate" comprehension. Cloze scores for the Grade 8 resource were lower for participants with less education (P = .047). Despite having satisfactory literacy test scores, results from interviews and focus groups revealed participants' limited understanding and misconceptions about PrCA risk. Many wanted information about screening and family history delivered word-of-mouth by AA women and church pastors as few of them had ever received or actively sought out PrCA resources. Using Nutbeam's framework, gaps in health literacy which were not adequately captured by the validated tools emerged during the interviews and focus groups. Study findings provide important implications for PrCA communication with AA men to correct misperceptions about cancer risk and motivate preventive behaviors.

Neuronal somatic ATP release triggers neuron–satellite glial cell communication in dorsal root ganglia

PubMed Central

Zhang, X.; Chen, Y.; Wang, C.; Huang, L.-Y. M.

2007-01-01

It has been generally assumed that the cell body (soma) of a neuron, which contains the nucleus, is mainly responsible for synthesis of macromolecules and has a limited role in cell-to-cell communication. Using sniffer patch recordings, we show here that electrical stimulation of dorsal root ganglion (DRG) neurons elicits robust vesicular ATP release from their somata. The rate of release events increases with the frequency of nerve stimulation; external Ca2+ entry is required for the release. FM1–43 photoconversion analysis further reveals that small clear vesicles participate in exocytosis. In addition, the released ATP activates P2X7 receptors in satellite cells that enwrap each DRG neuron and triggers the communication between neuronal somata and glial cells. Blocking L-type Ca2+ channels completely eliminates the neuron–glia communication. We further show that activation of P2X7 receptors can lead to the release of tumor necrosis factor-α (TNFα) from satellite cells. TNFα in turn potentiates the P2X3 receptor-mediated responses and increases the excitability of DRG neurons. This study provides strong evidence that somata of DRG neurons actively release transmitters and play a crucial role in bidirectional communication between neurons and surrounding satellite glial cells. These results also suggest that, contrary to the conventional view, neuronal somata have a significant role in cell–cell signaling. PMID:17525149

Fraile, Juan A.; Bajo, Javier; Abraham, Ajith; Corchado, Juan M.

Home Care is one of the main objectives of Ambient Intelligence. Nowadays, the disabled and elderly population, which represents a significant part of our society, requires novel solutions for providing home care in an effective way. In this chapter, we present HoCaMA, a hybrid multiagent architecture that facilitates remote monitoring and care services for disabled patients at their homes. HoCaMA combines multiagent systems and Web services to facilitate the communication and integration with multiple health care systems. In addition, HoCaMA focuses on the design of reactive agents capable of interacting with different sensors present in the environment, and incorporates a system of alerts through SMS and MMS mobile technologies. Finally, it uses Radio Frequency IDentification and JavaCard technologies to provide advanced location and identification systems, as well as automatic access control facilities. HoCaMA has been implemented in a real environment and the results obtained are presented within this chapter.

Complexin and Ca2+ stimulate SNARE-mediated membrane fusion

2008-01-01

Ca2+-triggered, synchronized synaptic vesicle fusion underlies interneuronal communication. Complexin is a major binding partner of the SNARE complex, the core fusion machinery at the presynapse. The physiological data on complexin, however, have been at odds with each other, making delineation of its molecular function difficult. Here we report direct observation of two-faceted functions of complexin using the single-vesicle fluorescence fusion assay and EPR. We show that complexin I has two opposing effects on trans-SNARE assembly: inhibition of SNARE complex formation and stabilization of assembled SNARE complexes. Of note, SNARE-mediated fusion is markedly stimulated by complexin, and it is further accelerated by two orders of magnitude in response to an externally applied Ca2+ wave. We suggest that SNARE complexes, complexins and phospholipids collectively form a complex substrate for Ca2+ and Ca2+-sensing fusion effectors in neurotransmitter release. PMID:18552825

Gap junction channels mediate intercellular signalling that is crucial in tissue development, homeostasis and pathologic states such as cardiac arrhythmias, cancer and trauma. To explore the mechanism by which Ca2+ blocks intercellular communication during tissue injury, we determined the X-ray crystal structures of the human Cx26 gap junction channel with and without bound Ca2+. The two structures were nearly identical, ruling out both a large-scale structural change and a local steric constriction of the pore. Ca2+ coordination sites reside at the interfaces between adjacent subunits, near the entrance to the extracellular gap, where local, side chain conformational rearrangements enable Ca2+chelation. Computational analysis revealed that Ca2+-binding generates a positive electrostatic barrier that substantially inhibits permeation of cations such as K+ into the pore. Our results provide structural evidence for a unique mechanism of channel regulation: ionic conduction block via an electrostatic barrier rather than steric occlusion of the channel pore.

Communication between the endoplasmic reticulum (ER) and mitochondrion is important for bioenergetics and cellular survival. The ER supplies Ca(2+) directly to mitochondria via inositol 1,4,5-trisphosphate receptors (IP3Rs) at close contacts between the two organelles referred to as mitochondrion-associated ER membrane (MAM). We found here that the ER protein sigma-1 receptor (Sig-1R), which is implicated in neuroprotection, carcinogenesis, and neuroplasticity, is a Ca(2+)-sensitive and ligand-operated receptor chaperone at MAM. Normally, Sig-1Rs form a complex at MAM with another chaperone, BiP. Upon ER Ca(2+) depletion or via ligand stimulation, Sig-1Rs dissociate from BiP, leading to a prolonged Ca(2+) signaling into mitochondria via IP3Rs. Sig-1Rs can translocate under chronic ER stress. Increasing Sig-1Rs in cells counteracts ER stress response, whereas decreasing them enhances apoptosis. These results reveal that the orchestrated ER chaperone machinery at MAM, by sensing ER Ca(2+) concentrations, regulates ER-mitochondrial interorganellar Ca(2+) signaling and cell survival.

Terbinafine inhibits gap junctional intercellular communication

Lee, Ju Yeun, E-mail: whitewndus@naver.com

Terbinafine is an antifungal agent that selectively inhibits fungal sterol synthesis by blocking squalene epoxidase. We evaluated the effect of terbinafine on gap junctional intercellular communication (GJIC). Fluorescence recovery after photobleaching (FRAP) and I-YFP GJIC assays revealed that terbinafine inhibits GJIC in a reversible and dose-dependent manner in FRT-Cx43 and LN215 cells. Treatment with terbinafine did not affect Cx43 phosphorylation status or intracellular Ca{sup 2+} concentration, well-known action mechanisms of various GJIC blockers. While a structurally related chemical, naftifine, attenuated GJIC, epigallocatechin gallate, another potent squalene epoxidase inhibitor with a different structure, did not. These results suggest that terbinafine inhibitsmore » GJIC with a so far unknown mechanism of action. - Highlights: • In vitro pharmacological studies were performed on FRT-Cx43 and LN215 cells. • Terbinafine inhibits gap junctional intercellular communication in both cell lines. • The inhibitory effect of terbinafine is reversible and dose-dependent. • Treatment of terbinafine does not alter Cx43 phosphorylation or cytosolic Ca{sup 2+} concentration. • Inhibition of squalene epoxidase is not involved in this new effect of terbinafine.« less

Calcium-loaded 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid blocks cell-to-cell diffusion of carboxyfluorescein in staminal hairs of Setcreasea purpurea.

The effect of microinjected calcium-loaded 1,2-bis(2-aminophenoxy) ethane-N,N,N',N'-tetraacetic acid (CaBAPTA) on cell-to-cell diffusion of carboxyfluorescein (CF) was examined in staminal hairs of S. purpurea Boom. The CaBAPTA was microinjected into the cytoplasm of the staminal hairs either with CF or prior to a subsequent microinjection of CF. The cell-to-cell diffusion of CF along the hair was monitored using enhanced-fluorescence video microscopy. Cytoplasmic streaming stopped in cells treated with CaBAPTA, indicating that intracellular Ca(2+) had increased. Cell-to-cell diffusion of CF was blocked in cells treated with Ca-BAPTA. An inhibition of cytoplasmic streaming and cell-to-cell diffusion was observed in the cells adjoining the CaBAPTA-microinjected cell, indicating that the Ca-BAPTA appeared to pass through plasmodesmata. While cytoplasmic streaming resumed 5-10 min after CaBAPTA treatment, cell-to-cell diffusion did not resume until 30-120 min later. These data support an involvement of calcium in the regulation of cell-to-cell communication in plants.

Active generation and propagation of Ca2+ signals within tunneling membrane nanotubes.

A new mechanism of cell-cell communication was recently proposed after the discovery of tunneling nanotubes (TNTs) between cells. TNTs are membrane protrusions with lengths of tens of microns and diameters of a few hundred nanometers that permit the exchange of membrane and cytoplasmic constituents between neighboring cells. TNTs have been reported to mediate intercellular Ca(2+) signaling; however, our simulations indicate that passive diffusion of Ca(2+) ions alone would be inadequate for efficient transmission between cells. Instead, we observed spontaneous and inositol trisphosphate (IP(3))-evoked Ca(2+) signals within TNTs between cultured mammalian cells, which sometimes remained localized and in other instances propagated as saltatory waves to evoke Ca(2+) signals in a connected cell. Consistent with this, immunostaining showed the presence of both endoplasmic reticulum and IP(3) receptors along the TNT. We propose that IP(3) receptors may actively propagate intercellular Ca(2+) signals along TNTs via Ca(2+)-induced Ca(2+) release, acting as amplification sites to overcome the limitations of passive diffusion in a chemical analog of electrical transmission of action potentials.

Visual attention and the apprehension of spatial relations: the case of depth.

PubMed

Moore, C M; Elsinger, C L; Lleras, A

2001-05-01

Several studies have shown that targets defined on the basis of the spatial relations between objects yield highly inefficient visual search performance (e.g., Logan, 1994; Palmer, 1994), suggesting that the apprehension of spatial relations may require the selective allocation of attention within the scene. In the present study, we tested the hypothesis that depth relations might be different in this regard and might support efficient visual search. This hypothesis was based, in part, on the fact that many perceptual organization processes that are believed to occur early and in parallel, such as figure-ground segregation and perceptual completion, seem to depend on the assignment of depth relations. Despite this, however, using increasingly salient cues to depth (Experiments 2-4) and including a separate test of the sufficiency of the most salient depth cue used (Experiment 5), no evidence was found to indicate that search for a target defined by depth relations is any different than search for a target defined by other types of spatial relations, with regard to efficiency of search. These findings are discussed within the context of the larger literature on early processing of three-dimensional characteristics of visual scenes.
